UBA20271规格书详情
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.
