PM6680A Datasheet Dual Step-down Controller

Manufacturer: STMicroelectronics

Overview: .. PM6680A Dual syncronous step-down controller with adjustable output voltages plus LDO Preliminary.

General Description

PM6680A is a dual step-down controller specifically designed to provide extremely high efficiency conversion, with losses current sensing technique.

The constant on-time architecture assures fast load transient response and the embedded voltage feed-forward provides nearly constant switching frequency operation.

An embedded integrator control loop pensates the DC voltage error due to the output ripple.

Key Features

  • 6V to 36V input voltage range Adjustable output voltages 5V LDO delivers 100mA peak current 1.237V ±1% reference voltage available externally Current sensing using low side MOSFETs RDS(on) Accurate current sense with RSENSE Valley current sensing Soft-start internally fixed at 2ms Soft output discharge Latched OVP and UVP Selectable pulse skipping at light loads Selectable minimum frequency (33kHz) i.
