It is a high-voltage and high-current step-down synchronous rectification DC-DC power management chip. It integrates functions such as a reference power supply, oscillator, error amplifier, current limiting protection, short-circuit protection, and half-bridge drive internally. It is suitable for applications in high-current scenarios, especially for the 5V output scenario. It supports the step-down synchronous rectification scheme. The operating frequency of 0 - 300KHz can be set by an external capacitor. It has functions such as UVLO (Under Voltage Lock Out) under-voltage lockout, cycle-by-cycle current limiting control, and output short-circuit hiccup protection. The package form is SOP16.
