ACT6391 2.5A PWM Step-Up DC/DC Converter In MSOP FEATURES Greater than 90% Efficiency Adjustable Output Voltages Up to 12V Internal 14V Power MOSFET 2.5A Peak Current Selectable 700kHz/1.3MHz Frequency Integrated Over-Voltage Protection (OVP) Programmable Soft-Start Function Thermal Shutdown Cycle-by-Cycle Over Current Protection Small MSOP-8 Package APPLICATIONS TFT LCD Monitors Battery-Powered Equipment Set-Top Boxes DSL and Cable Modems and Routers SIMPLIFIED APPLICATION CIRCUIT 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 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. The ACT6391 is available in the small 8-pin MSOP-8 package.
