uPI Semiconductor UP6182

The uP6182 is a dual synchronous buck controller with 5V/3.3V 100mA LDOs for notebook system power supply solution. 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.

GENERAL DESCRIPTION

A 250kHz VCLK output can be used for external charge pump to generate gate drive voltage for load switches. The adaptive on-time control provides a convenient and efficient operation. The uP6182 has internal soft-start to control the inrush current. The soft-stop feature avoids negative output voltage for undervoltage protection, overcurrent protection, and shutdown by discharging output through an internal switch, and by damping the inductor current. Supply input voltages ranging from 5.5V to 26V and output voltages from 2V to 5.5V. Other features include overcurrent protection, overvoltage protection, power-up sequencing, power OK output, and thermal shutdown. The uP6182 is available in the space saving package VQFN4x4-24L, specified from -40 OC to 85 OC.
