LTC1439CG Description

Short technical summary and product information.

The LTC1439CG from Analog Devices is a dual, synchronous step-down switching regulator controller designed to drive external N-channel power MOSFETs. It features a phase-lockable fixed frequency architecture and an Adaptive Power output stage that maintains high efficiencies even at low output currents by reducing switching losses.

 

This controller supports a wide input supply range from 3.5V to 30V, with a maximum of 36V. It offers ultrahigh efficiency and very low dropout operation with a 99% duty cycle. The device includes an auxiliary 0.5A linear regulator for VCC generation or low noise audio supply. Key control features include programmable soft start, a power-on reset timer, and a low-battery detector.

 

The LTC1439CG is available in a 36-lead SSOP package. It is suitable for applications such as notebook and palmtop computers, PDAs, portable instruments, battery-operated devices, and DC power distribution systems.
