产品描述
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 external
loop compensation and a pin-selectable
fixed-frequency of either 700kHz or 1.3MHz, allowing
optimization between component size, cost, and
AC performance across a wide range of applications.
Additional functions include an externally programmable
soft-start function for easy inrush current
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.
