uP1586 Dual Synchronous Buck Controller with 5V/3.3V 100mA LDOs for Notebook System Power General Description 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 combined POK signal. The ultrasonic mode maintains the switching frequency above audio frequency, which eliminates noise in audio applications. The proprietary RCOTTM technology provides fast transient response and high noise immunity. The uP1586 has internal soft-start to control the inrush current. Other features include overcurrent protection, overvoltage protection, power-up sequencing, power OK output, and thermal shutdown.
