Pin Definitions and Functions
Synchronization Input.
Connect to an external clock signal in order to synchronize/adjust the switching frequency.
If not used connect to GND.
Ground.
Compensation Input.
Frequency compensation for regulation loop stability.
Connect to compensation RC-network.
Feedback Input.
For the adjustable output voltage versions (IFX91041EJV) connect via voltage divider to output
capacitor.
For the fixed voltage version (IFX91041EJV50, IFX91041EJV33) connect this pin directly to the
output capacitor.
Buck Driver Supply Input.
Connect the bootstrap capacitor between this pin and pin BUO.
Buck Switch Output.
Source of the integrated power-DMOS transistor. Connect directly to the cathode of the catch
diode and the buck circuit inductance.
Enable Input.
Active-high enable input with integrated pull down resistor.
Supply Voltage Input.
Connect to supply voltage source.
Connect to heatsink area and GND by low inductance wiring.
