Description

550KHz, current mode PWM boost DC/DC converter

which could operate battery such as input voltage

down to 2.5V.

The converter output voltage can be

adjusted to a maximum of 5.25V by an external

resistor divider.

Besides the converter includes a

0.08Ω N-channel MOSFET switch and 0.12Ω

P-channel synchronous rectifier.

So no external

Schottky diode is required and could get better

efficiency near 93%.

The converter is based on a fixed frequency, current

mode, pulse-width-modulation PWM controller that

goes automatically into PSM mode at light load.

When converter operation into discontinuous mode,

the

internal

anti-ringing

switch

will

reduce

interference and radiated electromagnetic energy.

ilable in a space-saving SOT-23-6

package for portable application.
