Innovative Power TM TYPICAL APPLICATION CIRCUIT ACT4050 Wide Input 3.5A Step Down Converter Active-Semi Rev 2, 01-Jul-11 FEATURES • 3.5A Output Current • Up to 96% Efficiency • 4.5V to 15V Input Range • 12µA Shutdown Supply Current • 400kHz Switching Frequency • Adjustable Output Voltage From 0.817V • Cycle-by-Cycle Current Limit Protection • Thermal Shutdown Protection • Frequency Fold-Back at Short Circuit • Stability with Wide Range of Capacitors, Including Low ESR Ceramic Capacitors • SOP-8/EP (Exposed Pad) Package APPLICATIONS • Digital TV • Portable DVDs • Car-Powered or Battery-Powered Equipments • Set-Top Boxes • Telecom Power Supplies • Consumer Electronics GENERAL DESCRIPTION The ACT4050 is a current-mode step-down DC/DC converter that provides up to 3.5A of output current at 400kHz switching frequency. The device utilizes Active-Semi’s proprietary high voltage process for operation with input voltages up to 15V. The ACT4050 provides fast transient response and eases loop stabilization while providing excellent line and load regulation. This device features a very low ON-resistance power MOSFET which provides peak operating efficiency up to 96%. In shutdown mode, the ACT4050 consumes only 12μA of supply current. This device also integrates protection features including cycle-by-cycle current limit, thermal shutdown and frequency fold-back at short circuit. The ACT4050 is available in a SOP-8/EP (Exposed Pad) package and requires very few external devices for operation.
