The uP1586 is a dual synchronous buck controller with 5V/3.3V 100mA LDOs for notebook system power supply solution. The uP1586 supports high efficiency, fast transient response and provides a bined POK signal. The ultrasonic mode maintains the switching frequency above audio frequency, which eliminates noise in audio applications.
