ELM604PA _{1.4MHz, 800mA dual PWM step-down converter}

■General description

ELM604PA consists of dual high efficiency PWM step-down DC/DC converters operated with current

mode and constant frequency. For each converter the integration of a main switch and a synchronous rect-

ifier eliminates the use of an external Schottky diode. ELM604PA is ideal for the application of portable

electronic devices with a single cell Lithium-ion (Li+) battery. Each converter can supply 800mA of load curren

from a 2.5V to 6V input voltage. The output voltage can be regulated as low as 0.6V. It can also run at 100%

duty cycle for low dropout applications.
