Overview
UM3501 600mA, 1.
2MHz, Synchronous Step-Down DC-DC Converter UM3501 SOT23-5 UM3501DA DFN6L 2.
0×2.
0 General Description UM3501 is a high-efficiency pulse-width-modulated (PWM) step-down DC-DC converter, capable of delivering 600mA output current over a wide input voltage range from 2.
5V to 5.
5V.
The target application of UM3501 is 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 handy-terminals.
Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode.
No external Schottky diode is required in practical application.
The UM3501 automatically turns of...
