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.

Key Features

  • include over current protection, over/under voltage protection, power-up sequencing, POK output, and thermal shutdown. The uP1590 is available in the space saving package WQFN3x3-20L, specified from -40OC to 85OC.
