The UCC28C43QDRQ1 from Texas Instruments is a low-power, current-mode PWM controller suitable for automotive applications. It operates within a voltage range of 7.6V to 18V and supports topologies such as Boost, Flyback, and Forward converters.
This device features a maximum duty cycle of 100% and can operate at frequencies up to 1MHz. Key control features include frequency control, and it offers a low operating current of 2.3 mA at 52 kHz with a standby current of 50 µA. The controller includes fast 35-ns cycle-by-cycle over-current limiting and a 2.5V error amplifier reference.
Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, the UCC28C43QDRQ1 is AEC-Q100 qualified with temperature grade 1 (-40°C to 125°C). It is functional safety-capable, with documentation available to aid in functional safety system design.
