GENERAL DESCRIPTION
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.
