ACT4065A
High Input 2A Step Down Converter
GENERAL 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.
FEATURES
• 2A Output Current
• Up to 95% Efficiency
• 6.0V to 30V Input Range
• 210kHz Switching Frequency
• Adjustable Output Voltage
• Cycle-by-Cycle Current Limit Protection
• Thermal Shutdown Protection
• Frequency Foldback at Short Circuit
• Stability with Wide Range of Capacitors,
Including Low ESR Ceramic Capacitors
• SOP-8 Package
APPLICATIONS
• TFT LCD Monitors • Portable DVDs
• Car-Powered or Battery-Powered Equipments
• Set-Top Boxes • Telecom Power Supplies
• DSL and Cable Modems and Routers
• Termination Supplies
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. |
