uPI Confidential uP1590 Dual Synchronous Buck Controller with 5V/3.3V 100mA LDOs for Notebook System Power General Description The uP1590 is a dual synchronous buck controller with 5V/3.3V 100mA LDOs for notebook system power supply solution. The uP1590 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 uP1590 has internal soft-start to control the inrush current. Other features include over current protection, over/under voltage protection, power-up sequencing, POK output, and thermal shutdown.
