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
