UM3510 1A, 2.25MHz, Synchronous Step-Down DC-DC Converter UM3510S SOT23-6 UM3510DA DFN6 2.0×2.0 General Description The UM3510 is a high efficiency pulse-width-modulated (PWM) synchronous step-down DC-DC converter with an input voltage range of 2.5V to 6.0V. It provides up to 1000mA output current from a single Li-ion cell. The UM3510 operates at 2.25MHz fixed switching frequency and enters Power Save Mode to maintain high efficiency at light load condition. For low noise applications, the device can be forced into fixed frequency PWM mode by pulling the MODE pin high. The UM3510 enters shutdown mode and consumes less than 1μA when EN pin is pulled low. Other features include lower internal reference voltage with 2% accuracy, over temperature protection and over current protection.
