ACT6391 Overview
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 700kHz or 1.3MHz, allowing optimization between ponent size, cost, and AC performance across a wide range of...
