Dual High-Efficiency PWM Step-Down DC/DC Converter MT3820 GENERAL DESCRIPTION The MT3820 is a dual high-efficiency Pulse-Width-Modulated (PWM) step-down DC/DC converter. It is capable of delivering 1.2A output current over a wide input voltage range from 2.4V to 5.5V, the MT3820 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. No external Schottky diode is required in practical application.
