ADP3041 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, providing 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.
