MAX748A

Overview
19-0190; Rev 0; 9/93 3.
3V, Step-Down, Current-Mode PWM DC-DC Converters __________________General Description The MAX748A/MAX763A are 3.
3V-output CMOS, stepdown switching regulators.
The MAX748A accepts inputs from 3.
3V to 16V and delivers up to 500mA.
The MAX763A accepts inputs between 3.
3V and 11V and delivers up to 500mA.
Typical efficiencies are 85% to 90%.
Quiescent supply current is 1.
4mA (MAX763A), and only 0.
2µA in shutdown.
Pulse-width-modulation (PWM) current-mode control provides precise output regulation and excellent transient responses.
Output voltage accuracy is guaranteed to be ±5% over line, load, and temperature variations.
Fixed-frequency switching allows easy filtering o...
