Six-Channel, High-Efficiency, Digital

Camera Power Supplies

General Description

Features

The MAX1566/MAX1567 provide a complete power-

supply solution for digital cameras. They improve perfor-

mance, component count, and size compared to con-

ventional multichannel controllers in 2-cell AA,

1-cell lithium-ion (Li+), and dual-battery designs. On-chip

MOSFETs provide up to 95% efficiency for critical power

supplies, while additional channels operate with external

FETs for optimum design flexibility. This optimizes overall

efficiency and cost, while also reducing board space.

♦ 95% Efficient Step-Up DC-to-DC Converter

♦ 0.7V Minimum Input Voltage

♦ Main DC-to-DC Configurable as Either Step-Up or

Step-Down

♦ Combine Step-Up and Step-Down for 90%

Efficient Boost-Buck

♦ 95% Efficient Step-Down for DSP Core

♦ Regulate LED Current for Four, Six, or More LEDs

♦ Open LED Overvoltage Protection

The MAX1566/MAX1567 include six high-efficiency DC-

to-DC conversion channels:

• Step-up DC-to-DC converter with on-chip power FETs

♦ Transformerless Inverting Controller (MAX1567)

• Main DC-to-DC converter with on-chip FETs, config-

♦ Three Extra PWM Controllers (Two on the

urable to step either up or down

MAX1567)

• Step-down core DC-to-DC converter with on-chip

♦ Up to 1MHz Operating Frequency

♦ 1µA Shutdown Mode

♦ Soft-Start and Overload Protection

♦ Compact 40-Pin 6mm x 6mm Thin QFN Package

FETs

• DC-to-DC controller for white LEDs or other output

• Extra DC-to-DC controller (typically for LCD); two

extra controllers on the MAX1566

• Transformerless inverting DC-to-DC controller (typi-

cally for negative CCD bias) on the MAX1567

FUNCTION

PART

TEMP RANGE PIN-PACKAGE

All DC-to-DC channels operate at one fixed frequency

settable from 100kHz to 1MHz to optimize size, cost, and

efficiency. Other features include soft-start, power-OK

outputs, and overload protection. The MAX1566/

MAX1567 are available in space-saving 40-pin thin QFN

packages. An evaluation kit is available to expedite

designs.
