Product details

Current-mode PWM controller for multi-topology power stages

The Texas Instruments UCC38084PG4 is a current-mode PWM controller that handles step-up, step-down, and step-up/step-down topologies — buck, boost, half-bridge, or push-pull — from a single 4.1 V to 15 V supply rail. It drives two transistor outputs (positive configuration) at a fixed 200 kHz switching frequency, with a maximum duty cycle of 49%. The controller includes current limit and frequency control features, plus a synchronous rectifier drive output for efficiency. Packaged in an 8-pin PDIP (through-hole), it targets low-to-medium power offline and DC-DC converters where through-hole assembly or breadboard prototyping is preferred.

Through-hole PDIP-8 — prototype-friendly, board-area tradeoff

The 8-pin PDIP (0.300" wide, 7.62 mm pitch) is a standard through-hole footprint. It sockets into a breadboard or a drilled PCB without reflow.

Active lifecycle — no obsolescence pressure

The UCC38084PG4 carries an Active product status from Texas Instruments. There is no last-time-buy notice or NRND flag. The ROHS3 compliance covers current environmental requirements.

Frequently asked questions

What is the switching frequency of UCC38084PG4?

The switching frequency is fixed at 200 kHz. There is no external clock sync option — the oscillator runs free at that rate.

What is the maximum duty cycle of UCC38084PG4?

Maximum duty cycle is 49%. This prevents output pulse overlap in push-pull and half-bridge topologies, but also limits the step-down ratio in buck converters.
