The TPS54331 device is a 28-V, 3-A nonsynchronous buck converter that integrates a low RDS(on) high-side MOSFET. To increase efficiency at light loads, a pulse skipping Eco-mode feature is automatically activated. Furthermore, the 1-μA shutdown supply-current allows the device to be used in battery-powered applications. Current mode control with internal slope compensation simplifies the external compensation calculations and reduces component count while allowing the use of ceramic output capacitors. A resistor divider programs the hysteresis of the input undervoltage lockout. An overvoltage transient protection circuit limits voltage overshoots during start-up and transient conditions. A cycle-by-cycle current-limit scheme, frequency foldback and thermal shutdown protect the device and the load in the event of an overload condition. The TPS54331 device is available in an 8-pin SOIC package and 8-pin SO PowerPAD integrated circuit package that have been internally optimized to improve thermal performance. • 3.5 to 28-V input voltage range • Adjustable output voltage down to 0.8 V • Integrated 80-mΩ high-side MOSFET supports up to 3-A continuous output current • High efficiency at light loads with a pulse skipping Eco-mode • Fixed 570-kHz switching frequency • Typical 1-μA shutdown quiescent current • Adjustable slow-start limits inrush currents • Programmable UVLO threshold • Overvoltage transient protection • Cycle-by-cycle current limit, frequency foldback, and thermal shutdown protection • Available in easy-to-use SOIC8 package or thermally-enhanced SOIC8 PowerPAD™ integrated circuit package • Create a custom design using the TPS54331 with the WEBENCH® Power Designer • Use TPS62933 for a 30 VIN converter with higher frequency, lower IQ and improved EMI #CommonPartsLibrary #IntegratedCircuit #PowerManagement

The NE555 devices are precision timing circuits capable of producing accurate time delays or oscillation. In time-delay or monostable operating modes, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle are controlled independently with two external resistors and a single external capacitor. Each timer has a trigger level equal to approximately one-third of the supply voltage and a threshold level equal to approximately two-thirds of the supply voltage. These levels can be altered by use of the control voltage pin (CONT). When the trigger input (TRIG) is less than the trigger level, the flip-flop is set and the output goes high. If TRIG is greater than the trigger level and the threshold input (THRES) is greater than the threshold level, the flip-flop is reset and the output is low. The reset input (RESET) overrides all other inputs and is used to initiate a new timing cycle. If RESET is low, the flip-flop is reset and the output is low. Whenever the output is low, a lowimpedance path is provided between the discharge pin (DISCH) and the ground pin (GND). Tie all unused inputs to an appropriate logic level to prevent false triggering. The output circuit is capable of sinking or sourcing current up to 200mA. Operation is specified for supplies of 5V to 15V. With a 5V supply, output levels are compatible with TTL inputs. Features - Timing from microseconds to hours - Astable or monostable operation - Adjustable duty cycle - TTL-compatible output can sink or source up to 200mA - On products compliant to MIL-PRF-38535, all parameters are tested unless otherwise noted. Applications - Pulse-shaping circuits - Missing-pulse detectors - Pulse-width modulators - Pulse-position modulators - Sequential timers - Pulse generators -F requency dividers - Industrial controls

A simple voltage divider to showcase how to make parts. A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. Voltage dividers are one of the most fundamental circuits in electronics.
