Overview

FEATURES s s s s s s s LTC1538-AUX/LTC1539 Dual High Efficiency, Low Noise, Synchronous Step-Down Switching Regulators DESCRIPTION The LTC ®1538-AUX/LTC1539 are dual, synchronous stepdown switching regulator controllers which drive external N-channel power MOSFETs in a phase-lockable fixed frequency architecture.
The Adaptive PowerTM output stage selectively drives two N-channel MOSFETs at frequencies up to 400kHz while reducing switching losses to maintain high efficiencies at low output currents.
An auxiliary 0.
5A linear regulator using an external PNP pass device provides a low noise, low dropout voltage source.
A secondary winding feedback control pin (SFB1) guarantees regulation regard...
