Solutions for dimmable CFL/HFL-TL applications
UBA2014
The UBA2014 is a 600 V lamp controller and half-bridge driver
IC for dimmable CFL/HFL-TL applications. It makes dimmable
lights last longer and support energy-saving regulation while
lowering the total cost of ownership. The circuit is made in
a 650 V bipolar CMOS DMOS (BCD) power-logic process.
It provides the drive function for the two discrete power
MOSFETs. Besides the drive function, the IC also includes the
level-shift circuit, the oscillator function, a lamp voltage monitor,
a current-control function, a timer function, and protections.
In dimmable CFL applications, it offers adjustable pre-heat
time and pre-heat current, along with advanced dimming
functionality, including phase-cut and support for between 1
and 10 V. It also offers adaptive non-overlap time, integrated
bootstrap diodes, capacitive mode protection, lamp failure
detection, and power-down in case of lamp failure. In dimmable
HFL-TL applications, the device adds automatic re-start after
re-lamping, as well as lamp removal detection.
It is available in an evaluation kit that includes a 13 W TRIAC in
a dimmable CFL application. The kit supports 58 W TL designs,
and accepts inputs of 120/230 VAC or 500 VDC. Support from a
calculation tool is also available.
