Description:

Low voltage synchronous buck controller.

NCP1579, Low Voltage Synchronous Buck Controller

Pin No.

Symbol Description 1 BST Supply rail for the floating top gate driver.

To form a boost circuit, use an external diode to bring the desired input voltage to this pin (cathode connected to BST pin).

Connect a capacitor (CBST) between this pin and the PHASE pin.

Typical values for CBST range
