ML1565

Step-Up-Down DC-DC Converts

Digital Still camera Power Supply

High-Efficiency, 5-channel

ꢀ General Description

ꢀ Features

The ML1565 provides a complete power-supply solution

for digital still and video cameras through the integration

of ultra-high-efficiency step-up/step-down DC-to-DC con-

verters along with three auxiliary step-up controllers. The

ML1565 is targeted for applications that use either 2 or 3

alkaline or NiMH batteries as well as those using a single

lithium-ion (Li+) battery.

Step-Down DC-to-DC Converter:

Operate form Battery for 95% Efficient Buck

Combine with Step-Up for 90% Efficient Buck-Boost

Adjustable Output Down to 1.25V

Three Auxiliary PWM Controllers

Up to 1MHz Operating Frequency

1µA Shutdown Mode

The step-up DC-to-DC converter accepts inputs from 0.7V

to 5.5V and regulates a resistor-adjustable output from

2.7V to 5.5V. It uses internal MOSFETs to achieve

95% efficiency. Adjustable operating frequency facilitates

design for optimum size, cost, and efficiency.

ꢁ

Internal Soft-Start control

The step-down DC-to-DC converter can produce output

voltages as low as 1.25V and also utilizes internal

MOSFETs to achieve 95% efficiency. An internal softstart

ramp minimizes surge current form the battery. The

converter can operate from the step-up output providing

buck-boost capability with up to 90% compound efficiency,

or it can run directly from the battery if buck-boost

operation is not needed. The ML1565 features auxiliary

step-up controllers that power CCD, LCD, motor actuator,

and backlight circuits. The ML1565 is available in a

space-saving QFN-32 thin package.
