NCP1586 Datasheet (ON Semiconductor) - Low Voltage Synchronous Buck Controller

NCP1586, 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

NCP1586 Features

* of the gate driver include adaptive non

* overlap circuitry. The NCP1586 also incorporates an externally compensated error amplifier and a capacitor programmable soft

* start function. Protection features include programmable short circuit protection and under voltage lockout (UVLO). The
