MAX1802 Digital Camera Step-Down Power Supply

MAX1802 Description

19-1850; Rev 0; 10/00 Digital Camera Step-Down Power Supply General .
The MAX1802 provides a complete power-supply solution for digital still cameras and video cameras by integrating two high-efficiency step-down DC-DC c.

MAX1802 Features

* expandability by supplying power, an oscillator signal, and a reference to the MAX1801, a low-cost slave DC-DC controller that supports step-up, single-ended primary inductance converter (SEPIC), and fly-back configurations. The MAX1802 is available in a space-saving 32-pin TQFP package (5mm x 5mm b

MAX1802 Applications

* that use either three to four alkaline cells or two lithium-ion (Li+) cells. The main step-down DC-DC controller accepts inputs from 2.5V to 11V and regulates a resistor-adjustable output from 2.7V to 5.5V. It uses a synchronous rectifier to regulate the output with up to 94% efficiency. An adjustab
