UNISONIC TECHNOLOGIES CO., LTD UD06122 DUAL 1.2A 1.5MHz SYNCHRONOUS BUCK CONVERTER CMOS IC  DESCRIPTION The UTC UD06122 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 2.5V to 6.0V, the UTC UD06122 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. 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.
