Its 1kHz to 300kHz switching range lets you size the magnetics for cost or efficiency — lower frequencies for through-hole transformers, higher for planar or ferrite cores. The 97% maximum duty cycle means it can regulate down to near-zero dropout in a buck configuration, useful for post-regulation rails. Supply runs from 7V to 40V, covering 12V and 24V industrial buses, battery stacks, and unregulated bulk rails. Two transistor-driver outputs handle external MOSFETs or bipolars; dead-time and frequency control are on-chip. It fits outdoor telecom cabinets, factory-floor power supplies, motor-drive bias rails, and battery-charger controllers. The 16-TSSOP package is surface-mount, 4.40 mm wide — standard for automated assembly, but the fine pitch means visual inspection under magnification if reworking prototype boards. ## Active, no end-of-life concerns No LTB window, no NRND flag. ROHS3 compliant.","metaTitle":"TL594IPWR PWM Controller, 1kHz–300kHz, 97% Duty Cycle","metaDescription":"TL594IPWR is a multi-topology PWM controller from TI.
