Qorvo's ACT6391 is a high-performance, fixed-frequency, current-mode PWM step-up DC/DC converters that incorporate internal power MOSFETs. It includes an integrated 0.15 Ohm power MOSFET that supports currents of up to 2.5 A.
ACT6391 utilizes simple external loop compensation and a pin-selectable fixed-frequency of either 700 kHz or 1.3 MHz, 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.
ACT6391 is available in the small 8-pin MSOP-8 package.
