Description:

Low voltage synchronous buck controller.

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
