GENERAL DESCRIPTION

PGND

VCMO

The ADP3041 is a fixed frequency, PWM step-up dc-to-dc

switching regulator with five buffers capable of 12 V boosted

output voltage in a TSSOP 20-lead package. It provides high

efficiency, low noise operation, and excellent dynamic response,

and is easy to use. The high switching frequency allows for small,

cost-saving, external inductive and capacitive components. The

ADP3041 operates in PWM current mode. The current limit

and the power switch are integrated completely on-chip.

Capable of operating from 2.5 V to 5.5 V input, the ADP3041

is ideal for thin-film transistor (TFT) liquid crystal display

(LCD) module applications, where local point-of-use power

regulation is required. Supporting output voltages down to 4.5 V,

the ADP3041 is ideal to generate today’s low voltage rails, pro-

viding the optimal solution in its class for delivering power

efficiently, responsively, and simply with minimal printed circuit

board area.

The ADP3041 integrates five buffers. Each buffer can deliver

35 mA output current and has rail-to-rail input and output

capability.
