NCP81046 Datasheet - ON Semiconductor

NCP81046 Low Voltage Synchronous Buck Controller

Pin No. Symbol Description 1 BOOT 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 BOOT pin). Connect a capacitor (CBOOT) between this pin and the LX pin. Typical values for CBOOT r.

NCP81046 Features

* include a 1.5 A gate driver design and an internally set 300 kHz oscillator. In addition to the 1.5 A gate drive capability, other efficiency enhancing features of the gate driver include adaptive non

* overlap circuitry. The NCP81046 also incorporates an externally compensated error amplifier
