DESCRIPTIO
Accurate Preset +5V Output Up to 90% Efficiency Optional Burst Mode for Light Loads Can be Used with Many LTC Switching ICs Accurate Ultra-Low-Loss Current Limit Operates with Inputs from 6V to 30V Shutdown Mode Draws Only 15µA Uses Small 50µH Inductor
The LT1432 is a control chip designed to operate with the LT1170/LT1270 family of switching regulators to make a very high efficiency 5V step-down (buck) switching regulator. A minimum of external ponents is needed. Included is an accurate current limit which uses only 60mV sense voltage and uses “free” PC board trace material for the...
