CJ9460 Series 2A,4.5V-18V Input,500kHz Synchronous Step-Down Converter
The CJ9460 is a constant frequency, current mode step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. The output voltage can be regulated as low as 0.6V. The CJ9460 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load. The CJ9460 is offered in a low profile 6-pin, SOT package, and is available in an adjustable version.
