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.
