Product Overview

AP63205WU-7 is a high-performance wide-input voltage synchronous buck converter with a ultra-thin TSOT26 package, featuring a 3.8V~32V wide input voltage range and 5V fixed output voltage, and capable of delivering 2A continuous output current. The device integrates a 125mΩ high-side MOSFET and a 68mΩ low-side MOSFET, adopts peak current mode control with a built-in compensation network, and achieves EMI optimization through ±6% Frequency Spread Spectrum (FSS) and a proprietary gate driver scheme. With a quiescent current as low as 22μA and compliance with RoHS lead-free environmental standards, it is an ideal step-down power supply solution for scenarios such as 12V/24V distributed power supplies, flat-panel TVs, power tools, and set-top boxes.

• EMI-optimized design: Integrates ±6% frequency spread spectrum and patented ringing-free switching node technology to significantly reduce electromagnetic interference
• Low-power operation: 22μA ultra-low quiescent current with 88% efficiency at light load (5mA), balancing energy saving and battery life
• Comprehensive protection mechanism: Built-in undervoltage lockout, cycle-by-cycle peak current limiting, overvoltage protection and thermal shutdown functions to improve system reliability

Technical Specifications

Typical Applications

1. 12V/24V Distributed Power Buses

In industrial 12V/24V distributed power systems, the 3.8V~32V wide input of AP63205WU-7 can tolerate bus voltage fluctuations, and the 2A output capability can provide stable 5V power for core devices such as FPGAs and DSPs. The EMI-optimized design avoids power noise interfering with industrial control signals, ensuring the stability of system communication and computing.

2. Flat-Panel TVs and Monitors

For the step-down circuit of flat-panel TV power boards, the 1.1MHz high-frequency switching of the device can reduce the size of inductors and capacitors, adapting to the compact PCB layout inside the TV. The 5V precise output can provide stable power for the driver board and decoding module, and the low-EMI feature can eliminate the impact of power interference on display signals and avoid screen flickering or noise.

3. Power Tools and Laser Printers

In the battery power supply system of power tools and the control circuit of laser printers, the wide input range of AP63205WU-7 can adapt to the wide voltage variation of batteries (such as the discharge range of 24V batteries). The 2A output current can meet the power demand of motor drive auxiliary circuits and print control modules, and the comprehensive protection mechanism can cope with instantaneous current shocks during tool startup and shutdown.

4. Set-Top Boxes and Gaming Consoles

For the power supply modules of consumer electronics such as set-top boxes and gaming consoles, the low quiescent current of the device can reduce the standby power consumption of the equipment, and the high light-load efficiency improves battery life. The EMI-optimized design can pass electromagnetic compatibility certification, avoiding power interference affecting the transmission of radio frequency signals and game signals, and ensuring the smooth operation of the equipment.

5. White Goods Control Circuits

In the power supply circuits of main control units and sensors of white goods such as refrigerators and washing machines, the -40℃~+85℃ wide temperature range of AP63205WU-7 can adapt to the complex working environment of home appliances. The 32V high input voltage withstand capability can resist instantaneous overvoltage of the power grid, and the 2A output capability can power multiple sensors and control chips at the same time, improving the integration of home appliance control systems.
