The uP6182 is a dual synchronous buck controller with 5V/3.3V 100mA LDOs for notebook system power supply solution. A 250kHz VCLK output can be used for external charge pump to generate gate drive voltage for load switches. The uP6182 supports high efficiency, fast transient response and a combined power-good signal. The out of audio mode maintains the switching frequency above audio frequency, which eliminates noise in audio applications. The adaptive on-time control provides a convenient and efficient operation.
