Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- TinySwitch-III incorporates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry.
- Pin Configuration.** It is the connection point for an external bypass capacitor for the internally generated 5.85 V supply.
- When the current into the BP/M voltage drops below 4.9 V , during a power down.
- Frequency Jitter.** threshold current is between 60 µA and 115 µA.
- The controller consists of an oscillator, enable circuit (sense and logic), current limit state machine, 5.85 V regulator, BYPASS/ MULTI-FUNCTION pin under-voltage, overvoltage circuit, and current limit selection circuitry, over- temperat.
- TinySwitch-III incorporates additional circuitry for line under-voltage sense, auto-restart, adaptive switching cycle on-time extension, and frequency jitter.
- Oscillator The typical oscillator frequency is internally set to an average of 132 kHz.

Engineering review checklist
- Confirm repetitive reverse voltage, average forward current, surge current and leakage at the intended temperature.
- Check forward-voltage loss and reverse-recovery behavior at the actual current and switching frequency.
- Review package thermal resistance, copper area, polarity marking and transient derating before layout release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
