GENERAL DESCRIPTION

The ACT6390/ACT6391 are high-performance,

fixed-frequency,

current-mode

PWM

step-up

DC/DC converters that incorporate internal power

MOSFETs. The ACT6390 includes an integrated

0.2Ω power MOSFET that supports peak currents

of up to 1.7A, while the ACT6391’s integrated

0.15Ω power MOSFET supports currents of up to

2.5A.

The ACT6390 and ACT6391 both utilize simple ex-

ternal loop compensation and a pin-selectable

fixed-frequency of either 700kHz or 1.3MHz, allow-

ing optimization between component size, cost, and

AC performance across a wide range of applica-

tions. Additional functions include an externally pro-

grammable soft-start function for easy inrush cur-

rent control, internal over-voltage protection (OVP),

cycle-by-cycle current limit protection, and thermal

shutdown.

Both the ACT6390 and the ACT6391 are available

in the small 8-pin MSOP-8 package.
