UP6182 - uPI Semiconductor

UP6182 Dual Synchronous Buck Controller

The uP6182 is a dual synchronous buck controller with 5V/3.3V 100mA LDOs for notebook system power supply solution. A 250kHz VCLK output can be used for external charge pump to generate gate drive voltage for load switches. The uP6182 supports high efficiency, fast transient response and a combined power-good signal. The out of audio mode maintains the switc.

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. † Two Synchronous Buck Controllers † Output Voltage Range: 2V to 5.5V † Selectable Audio Mode in Light Load † Internal 1.6ms Output Voltage Softstart † Adaptive On Time Control Architecture † 4500ppm/OC RDS(ON) Current Sensing † 100mA 5V/3.3V LDO with Switches † 1% 2V Reference Voltage Output † Power Good Output † OVP/UVP/OCP † Thermal Shutdown † VQFN4x4-24L † RoHS Compliant and 100% .
