UBA20271/2

350 V and 600 V Power ICs for dimmable compact fluorescent

lamps

Rev. 2.1 — 12 October 2011

Product data sheet

1. General description

The UBA20271/2 are high-voltage power ICs intended to drive and control higher

powered self ballasted Compact Fluorescent Lamp (CFL) lighting applications. The

UBA20271/2 operate from 120 V and 230 V. The module includes a half-bridge power

circuit of two NMOST power FETs. In addition, a controller circuit is included that has

advanced features for dimming and a lamp current controlled boost feature. The boost

feature is used for boosting cold (amalgam) CFL.

The controller contains a half-bridge drive function for CFL, a high-voltage level-shift

circuit with integrated bootstrap diode. In addition, the controller contains an oscillator

function, a current control function both for preheat and burn, a timer function and

protection circuits. The UBA20271/2 are supplied via a dV/dt current charge supply circuit

from the half-bridge circuit.

Remark: Mains voltages noted are AC.
