DESCRIPTIONDesign goals for a cold cathode fluorescent lamp
(CCFL) converter used for a liquid crystal display
(LCD) monitor application include small size, high
efficiency, and low cost. The UCC2974/UCC3974
CCFL controllers provide the necessary circuit
blocks to implement a highly efficient LCD monitor
backlight supply in a small 16-pin TSSOP
package. The device features two control stages
for operating independent resonant tanks for
multi-lamp designs. The BiCMOS controller
typically consumes less than 2-mA of operating
current, improving overall system efficiency.
External parts count is minimized and system cost
is reduced by integrating such features as dual
PWM driver stages, open lamp protection,
overvoltage clamp, and synchronization circuitry
between the buck and push-pull stages. The
device operates in both analog and low-frequency
dimming modes.
