WWW.ORIENT-CHIP.COM OCP2153 1.5MHz, 1.5A Synchronous Step-Down DC-DC Converter ◼ General Description The OCP2153 is a 1.5MHz constant frequency, high efficiency, high current, slope compensated current mode PWM step-down DC-DC converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The OCP2153 can operate from a 2.5V to 5.5V input voltage and is ideal for powering portable equipment that runs from a single cell lithium-Ion (Li+) battery. It can supply 1.5A output current and can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. Pulse Skipping Mode operation at light loads provides very low output ripple voltage for noise sensitive applications. The OCP2153 is offered in small profile 6 -Lead DFN packages, and is available in an adjustable version and fixed output voltage of 1.2V,1.5V,1.8V and 3.3V. ◼ Applications ⚫ Portable Instruments ⚫ Digital Cameras .
