GENERAL DESCRIPTION
The ACT6391 is a high-performance, fixed-frequency, current-mode PWM step-up DC/DC converter that incorporates internal power MOSFETs. The ACT6391’s integrated 0.15Ω power MOSFET supports currents of up to 2.5A.
The ACT6391 utilizes simple external loop pensation and a pin-selectable fixed-frequency of either 700k Hz or 1.3MHz, allowing optimization between ponent 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.
The ACT6391 is available in the small 8-pin MSOP-8 package.
