Buck Switching Regulator IC Positive Adjustable 0.8V 1 Output 3A 10-VFDFN Exposed Pad The TPS5433xA family of devices are synchronous converters with an input-voltage range of 4.5 V to 28 V. These devices include This device has an integrated low-side switching FET that eliminates the need for an external diode which reduces component count. Efficiency is maximized through the integrated 128- mΩ and 84-mΩ MOSFETs, low IQ and pulse skipping at light loads. Using the enable pin, the shutdown supply current is reduced to 2 μA. This step-down (buck) converter provides accurate regulation for a variety of loads with a well-regulated voltage reference that is 1.5% over temperature. Cycle-by-cycle current limiting on the high-side MOSFET protects the TPS5433xA family of devices in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. A low-side sinking current-limit turns off the low-side MOSFET to prevent excessive reverse current. Hiccup protection is triggered if the overcurrent condition continues for longer than the preset time. Thermal shutdown disables the device when the die temperature exceeds the threshold and enables the device again after the built-in thermal hiccup time. • Synchronous 128-mΩ and 84-mΩ MOSFETs for 3-A Continuous Output Current • TPS54335A: Internal 2-ms Soft-Start, 50-kHz to 1.5-MHz Adjustable Frequency • TPS54336A: Adjustable Soft-Start, Fixed 340-kHz Frequency • Low 2-µA Shutdown, Quiescent Current • 0.8-V Voltage Reference with ±0.8% Accuracy • Current Mode Control • Monotonic Startup into Pre-Biased Outputs • Pulse Skipping for Light-Load Efficiency • Hiccup Mode Overcurrent Protection • Thermal Shutdown (TSD) and Overvoltage Transition Protection • 8-Pin SO PowerPAD™ and 10-Pin VSON Package • Create a Custom Design Using the TPS54335A with the WEBENCH Power Designer #CommonPartsLibrary #IntegratedCircuit #PowerManagement

It combines multiple protection and control features into a single solution, enabling safe distribution of power to downstream circuitry while minimizing the need for external components. The device supports controlled inrush current during startup, continuous current monitoring, and rapid fault response to protect both the power source and the load. Integrated protection mechanisms include overvoltage protection, undervoltage lockout, overcurrent limiting, thermal shutdown, and reverse current blocking. This makes the device well suited for applications requiring high reliability, such as embedded systems, industrial electronics, consumer devices, and communication equipment. Functional Description The device operates as a high-side protection switch using an internal MOSFET to control current flow from the input supply to the load. It monitors input voltage, output current, and internal temperature to ensure operation within safe limits. When a fault condition such as overcurrent or overvoltage is detected, the device limits or interrupts current flow to prevent damage. The integrated control loop provides smooth startup by limiting inrush current and preventing supply droop. Reverse current blocking prevents unwanted current flow from the output back to the input when the input supply is removed or drops below the output level. Electrical Characteristics The device supports operation across a wide input voltage range suitable for low-voltage DC systems, including typical five-volt rails. It features an adjustable overvoltage protection threshold aligned with five-volt system requirements, along with configurable undervoltage lockout to ensure proper system startup and shutdown behavior.

The device exhibits low on-resistance to minimize power dissipation and voltage drop during normal operation. Protection Features The TPS259530DSGR integrates multiple protection functions to enhance system robustness. Overvoltage protection prevents excessive input voltage from reaching the load. Undervoltage lockout ensures the device only operates when the input supply is within a valid range. Overcurrent protection actively limits current during fault conditions and can respond rapidly to short circuits. Thermal shutdown protects the device from overheating by disabling operation when internal temperature exceeds safe limits. Reverse current blocking prevents backflow of current, safeguarding both the source and load. Control and Interface The device includes an enable control input that allows external control of the power path. It supports configurable behavior for fault response and recovery, depending on system design. External components can be used to set thresholds such as current limit and undervoltage lockout, providing design flexibility. Status signaling allows system-level monitoring of fault conditions.

Polymeric PTC Resettable Fuse 16V 3 A Ih Through Hole Radial, Disc # Engineering Specification ## Product Name RGEF300 ## General Description RGEF300 is a resettable polymeric positive temperature coefficient protection device designed to safeguard electronic circuits against overcurrent and fault conditions. The component is intended for use in power distribution systems, low-voltage DC rails, and electronic assemblies where temporary overload protection and automatic recovery are required. The device operates by increasing its internal resistance when subjected to excessive current or elevated temperature conditions, thereby limiting fault current and protecting downstream circuitry. Once the fault condition is removed and the device cools, it returns to a low-resistance state, allowing normal operation to resume without the need for manual replacement. RGEF300 is widely used in industrial electronics, consumer devices, automotive subsystems, communication equipment, and embedded systems where reliable overcurrent protection and system uptime are critical. Its radial-leaded configuration supports straightforward integration into through-hole PCB designs and legacy circuit architectures.
