OCP2153
OCP2153 is 1.5A Synchronous Step-Down DC-DC Converter manufactured by ORIENT-CHIP.
- Part of the OCP2153-ORIENT comparator family.
- Part of the OCP2153-ORIENT comparator family.
Description
- Features
The OCP2153 is a 1.5MHz constant frequency, high
- High Efficiency : Up to 96% efficiency, high current, slope pensated current
- 1.5MHz Constant Switching Frequency mode PWM step-down DC-DC converter. The
- 1.5A Output Current device integrates a main switch and a synchronous
- 2.5V to 5.5V Input Voltage Range rectifier for high efficiency without an external
- Output Voltages from 0.6V to 5V
Schottky diode. The OCP2153 can operate from a
- Low RDS(ON) Internal Switches: 72mΩ(Typ.)
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
M 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
O loads provides very low output ripple voltage for noise sensitive applications.
.C 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.
