MOSFETs arranged in a half-bridge configuration with

only one input.

This document describes how the NCP5104 driver can be

The NCP5104 is a high voltage power MOSFET driver

It uses the bootstrap technique to insure a proper drive of

Input range : 85 Vac - 145 Vac OR 184 Vac - 265 Vac

Ballast Output Power : 36 W (type PL-L 36W)

Pre-Heating Current : 295 mA

Pre-Heating Time : 1 second

Nominal Current : 414 mA

NOTE: BEFORE PLUGGING IN THE DEMO BOARD,

MAKE SURE THE JUMPER IS ON THE CORRECT

POSITION: IF J2 IS USED, THEN Vin MUST BE

LOWER THAN 145 Vac.

Detailed Operation

configuration. The 2 power MOSFETs are driven with the

NCP5104 driver. The driver is supplied by the V

the high side driver is supplied by the bootstrap diode: when

the low side power MOSFET (Q2) is switched ON, the

BRIDGE pin is pulled down to the ground, thus the capacitor

connected between BRIDGE pin and VBOOT pin is

refuelled via the diode D3 and the resistor R5 connected to

supplies the high side driver with a voltage equal to V

level minus the D3 forward voltage diode. Given the

NCP5104 architecture, the driver copies the input signal to

the high side driver, then it generates a fixed dead time

(520 ns) before toggling the low side driver when the input

pin level changes.

The lamp ballast is powered via a half bridge

. When Q2 is switched OFF the bootstrap capacitor C6
