Datasheet Summary
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 bined 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...
