TinySwitch-III incorporates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability.
Simple ON/OFF control, no loop compensation needed
Selectable current limit through BP/M capacitor value
Maximizes MOSFET and magnetics power delivery
Minimizes max overload power
ON-time extension
Self-biased: no bias winding or bias components
Frequency jittering reduces EMI filter costs
Pin-out simplified es heatsinking to the PCB

Electronics 109: Power Integrity & Brownout Debugging
A real-world engineering guide to diagnosing unstable electronics: brownouts, random resets, noisy sensors, USB dropouts, and the hidden power integrity issues that cause “software bugs” which aren’t software bugs at all.
