Diodes Incorporated AP62150 Synchronous Buck Converter fully integrates a 90mΩ high-side power MOSFET and a 65mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. The 1.5A AP62150 synchronous buck converter features a wide input voltage range of 4.2V to 18V and an output voltage range of 0.8V to 7V.
External component count is minimized on the Diodes Inc. AP62150, implemented by the Constant On-Time (COT) control. The COT achieves a fast transient response, smooth loop stabilization, and low output voltage ripple. Additionally, the AP62150 is optimized for Electromagnetic Interference (EMI) reduction.
The device has a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times. This reduces high-frequency radiated EMI noise caused by MOSFET switching.
The AP62150 offers protection circuitry such as under-voltage lockout (UVLO), cycle-by-cycle valley current limit, and thermal shutdown. The AP62150 is available in SOT563 and TSOT26 packages.
