NCP1586 Datasheet - ON Semiconductor

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
