Ordering Information

Description

The FP6790 is a step-up current mode PWM DC/DC

converter with an internal 1.6A, 0.25

Ω N-channel

MOSFET.

Pin selectable fixed switching frequency

(1.2MHz or 640kHz) and external compensation pin

provide the user flexibility in setting the loop

dynamic, allowing the use of tiny, low profile

inductors and low value, low ESR ceramic output

capacitors.

The FP6790 provides soft-start feature which is

programmable with an external capacitor.

In

shutdown mode, current consumption is reduced to

only 0.1

μA. The FP6790 converts the input voltage

ranged from 2.6V to 5.5V into an output voltage up to

12V.

FP6790 is available in the space-saving MSOP-8

package.
