Product details

Device identity and topology flexibility

The TL594CPW is a PWM controller from Texas Instruments that supports step-up, step-down, and step-up/step-down topologies — buck, boost, flyback, forward converter, full-bridge, half-bridge, and push-pull. It operates from a 7 V to 40 V supply rail and delivers two transistor-driver outputs with a max duty cycle of 97%. The switching frequency spans 1 kHz to 300 kHz, with no clock sync input.

Housed in a 16-TSSOP (4.40 mm width) surface-mount package, supplied in tube form.

Frequently asked questions

How can I order TL594CPW or check stock?

The TL594CPW is an active part sourced to order against an RFQ.

What is the closest functional second-source for TL594CPW — UCC2806DWTR?

The UCC2806DWTR is a peer PWM controller with similar topology support (boost, flyback, forward) but differs in key specs: it has a 50% max duty cycle (vs 97%), a fixed 47 kHz switching frequency (vs 1-300 kHz), and an 8 V supply minimum (vs 7 V). It also includes synchronous rectifier capability and a wider temperature range (-40°C to 85°C). The TL594CPW offers broader frequency and duty-cycle flexibility for designs needing higher duty cycles or adjustable switching.

What compliance documentation does Texas Instruments provide for TL594CPW?

The TL594CPW is ROHS3 compliant per Texas Instruments.
