Description

ACT4065A

High Input 2A Step Down Converter

High Input 2A Step Down Converter 2A Output Current Up to 95% Efficiency 210kHz Switching Frequency ACT4065ASHGENERAL DESCRIPTION

The ACT4065A is a current-mode step-down DC/DC converter that generates up to 2A output current at 210kHz switching frequency. The ACT4065A is highly efficient with peak efficiency at 95% when in operation. Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency foldback at short circuit. The ACT4065A is available in SOP-8 package and requires very few external devices for operation.

PIN DESCRIPTION

PIN NUMBER PIN NAME PIN DESCRIPTION
1 BS Bootstrap. This pin acts as the positive rail for the high-side switch’s gate driver. Connect a 10nF between this pin and SW.
2 IN Input Supply. Bypass this pin to G with a low ESR capacitor. See Input Capacitor in Application Information section.
3 SW Switch Output. Connect this pin to the switching end of the inductor.
4 G Ground.
5 FB Feedback Input. The voltage at this pin is regulated to 0.808V. Connect to the resistor divider between output and ground to set output voltage.
6 COMP Compensation Pin. See Compensation Techniques in Application Information section.
7 EN Enable Input. When higher than 0.8V, this pin turns the IC on. When lower than 0.8V, this pin turn the IC off. Output voltage is discharged when the IC is off. This pin has a small internal pull-up current to a high level voltage when pin is not connected. Do not allow EN pin to exceed 6V.
8 N/C Not Connected.
