AX3515A Dual High-Efficiency PWM Step-Down DC-DC Converter
GENERAL DESCRIPTION The AX3515A is a dual high-efficiency Pulse-Width-Modulated (PWM) step-down DC-DC converter.
It is capable of delivering 1A output current over a wide input voltage range from 2.
5V to 5.
5V, the AX3515A is ideally suited for portable electronic devices that are powered from 1-cell Li-ion battery or from other power sources within the range such as cellular phones, PDAs and other handheld devices.
Two operational modes are available: PWM/Low-Dropout auto-switch and shutdown modes.
Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode.
