The MC34067P from ON Semiconductor is a high-performance resonant mode controller designed for off-line and DC-to-DC converter applications. It utilizes frequency modulated constant off-time or constant deadtime control.
This controller features a variable frequency oscillator with a control range exceeding 1000:1, a precision one-shot timer for controlled off-time, and a temperature-compensated reference. It includes a high gain, wide bandwidth error amplifier, a steering flip-flop, and dual high current totem pole outputs suitable for driving power MOSFETs. Protective features include a high-speed fault comparator and latch, programmable soft-start circuitry, and selectable input undervoltage lockout thresholds with hysteresis.
The MC34067P is available in a 16-PDIP package and is designed for through-hole mounting. It operates within a voltage range of 8.6V to 20V and has an operating temperature range of 0°C to 70°C.
Key electrical specifications include a frequency of 2.05MHz, 2 outputs, and a flyback topology. It supports functions like Step-Up/Step-Down conversion and features like Enable and Soft Start control.
