Product details

Active production — AEC-Q100 current mode PWM controller for automotive power supplies

The UC2842AQD8: The controller supports boost, buck, flyback, and forward topologies with a single transistor-driver output, and its 96% maximum duty cycle allows high step-down ratios without pulse skipping.

Switching frequency and thermal range for harsh environments

Switching frequency reaches up to 500 kHz, which lets the designer shrink the magnetic components — a 200 kHz flyback transformer is roughly half the volume of a 100 kHz design. The 8-SOIC package (0.154" width, 3.90 mm body) is a standard surface-mount footprint that reflows on a standard lead-free profile.
