12V to fixed 5V 2A Non-Synchronous Step-Down Regulator. The TPS5405 is a monolithic non-synchronous buck regulator with wide operating input voltage range from 6.5 V to 28 V. Current mode control with internal slope compensation is implemented to reduce component count. TPS5405 also features a light load pulse skipping mode, which allows for a power loss reduction from the input power supply to the system at light loading. The switching frequency of the converters can be set from 50 kHz to 1.1 MHz with an external resistor. Frequency spread spectrum operation is introduced for EMI reduction. LX anti-ringing is added to address high frequency EMI issues. A cycle-by-cycle current limit with frequency fold back protects the IC at over loading condition.

Buck Switching Regulator IC Positive Fixed 3.3V 1 Output 2A SOT-23-6 Thin, TSOT-23-6 The AP63200/AP63201/AP63203/AP63205 is a 2A, synchronous buck converter with a wide input voltage range of 3.8V to 32V and fully integrates a 125mΩ high-side power MOSFET and a 68mΩ low-side power MOSFET to provide high-efficiency step-down DC/DC conversion. The AP63200/AP63201/AP63203/AP63205 device is easily used by minimizing the external component count due to its adoption of peak current mode control along with its integrated compensation network. The AP63200/AP63201/AP63203/AP63205 has optimized designs for Electromagnetic Interference (EMI) reduction. The converter features Frequency Spread Spectrum (FSS) with a switching frequency jitter of ±6%, which reduces EMI by not allowing emitted energy to stay in any one frequency for a significant period of time. It also has a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which further erases highfrequency radiated EMI noise caused by MOSFET switching. The device is available in a low-profile, TSOT26 package. • VIN 3.8V to 32V • 2A Continuous Output Current • 0.8V ±1% Reference Voltage • 22µA Ultralow Quiescent Current • Switching Frequency o 500kHz: AP63200 and AP63201 o 1.1MHz: AP63203 and AP63205 • Pulse Width Modulation (PWM) Regardless of Output Load o AP63201 • Supports Pulse Frequency Modulation (PFM) o AP63200, AP63203, and AP63205 o Up to 80% Efficiency at 1mA Light Load o Up to 88% Efficiency at 5mA Light Load • Fixed Output Voltage o 3.3V: AP63203 o 5.0V: AP63205 • Proprietary Gate Driver Design for Best EMI Reduction • Frequency Spread Spectrum (FSS) to Reduce EMI • Precision Enable Threshold to Adjust UVLO • Protection Circuitry o Overvoltage Protection o Cycle-by-Cycle Peak Current Limit o Thermal Shutdown • 12V and 24V distributed power bus supplies • Flat screen TV sets and monitors • Power tools and laser printers • White goods and small home appliances • FPGA, DSP, and ASIC supplies • Home audios • Network systems • Set top boxes • Gaming consoles • Consumer electronics #commonpartslibrary #integratedcircuit #AP63203WU7 #BuckConverter #DCDCConverter #PowerManagement #VoltageRegulator #SynchronousBuck #EmbeddedSystems #IndustrialElectronics #PowerSupply #DiodesInc #3V3Power #ElectronicsDesign
