Overview
LTC1436A LTC1436A-PLL/LTC1437A High Efficiency Low Noise Synchronous Step-Down Switching Regulators DESCRIPTION The LTC®1436A/LTC1437A are synchronous step-down switching regulator controllers that 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 (SFB) guarantees regulation regardless of the load on the main ...
