NCP1583, NCP1582, 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
