一.产品概述
The CXSD6120 is a 1.4MHz constant frequency, slope compensated current
mode PWM stepdown 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 CXSD6120 can supply 600mA of load current from
a 2.0V to 5.5V input voltage. The output voltage can be regulated as low as
0.6V. The CXSD6120 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 CXSD6120 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.
