800mA 1.4MHz

ELM600LA

high efﬁciency synchronous PWM step down DC/DC converter

■General description

ELM600LA is high efﬁciency synchronous step down DC/DC converter operated with current mode and 1.4MHz

constant frequency; internal switch and synchronous rectiﬁer are integrated for high efﬁciency. In application,

ELM600LA does not require any external Schottky diode. Internal current consumption under operation of

ELM600LA is as low as 200µA and drops to less than 1µA in shutdown mode. With supply voltage from 2.5V

to 6V, ELM600LA can supply load current of 800mA; the output voltage can be regulated as low as 0.6V.

With 1.4MHz switching frequency, ELM600LA makes it possible to adopt small surface amount inductors and

capacitors. Switch duty cycle would be on continuously and 100% at maximum when input voltage is set be to

lower than output voltage.
