LSP5527 is A current control mode synchronous buck regulator that provides continuous 2.1A load current, with transient response, uninterrupted overcurrent detection, soft start, low voltage protection, overtemperature protection, overcurrent protection and other functions, standby current is only 0.3μA, its pin functions are:
①, ⑤ feet (BS), self-lifting pressure;
② Pin (VIN), power supply input;
③ foot, switch output;
④ feet, GND; 5 pin (FB), feedback input;
⑥ Foot (Comp), compensation port;
⑦ Foot (EN), enable input;
⑧ Pin (SS), soft boot port.
