Step-down synchronous rectification DCDC power chip
High-voltage and high-current step-down 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-voltage and high-current scenarios. When used with an external high-voltage MOS tube, it can support a maximum input power supply voltage of 600V. It adopts a synchronous rectification scheme. The operating frequency of 10KHz - 100KHz 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 protection. The package form is SOP16.
