OCP2157
Key Features
- High Efficiency : Up to 96% compensated current mode PWM step-down
- 1.5MHz Constant Switching Frequency converter. The device integrates a main switch and a
- 700mA Output Current at VIN=3.0V synchronous rectifier for high efficiency without an
- Integrated Main switch and synchronous rectifier. external Schottky diode. It is ideal for powering No Schottky Diode Required portable equipment that runs from a single cell
- 2.5V to 5.5V Input Voltage Range lithium-Ion (Li+) battery. The OCP2157 can supply 700mA of load current from a 2.5V to 5.5V input voltage. The output voltage can be regulated as low as M 0.6V. The OCP2157 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. Idle mode operation at light loads O provides very low output ripple voltage for noise sensitive applications. .C The OCP2157 is offered in a low profile (1mm) 5-pin, SOT package, and is available in an adjustable version and fixed output voltage of 1.2V, 1.5V and 1.8V.
