MC33023 Datasheet | onsemi

MC34023, MC33023 High Speed Single-Ended PWM Controller The MC34023 series are high speed, fixed frequency, single- ended pulse width modulator controllers optimized for high frequency operation. They are specifically designed for Off- Line and DC- to- DC converter applications offering the designer a cost- effective solution with minimal external ponents. These integrated circuits feature an oscillator, a temperature pensated reference, a wide bandwidth error amplifier, a high speed current sensing parator, and a high current totem pole output ideally suited for driving a power MOSFET. Also included are protective Features consisting of input and reference undervoltage lockouts each with hysteresis, cycle- by- cycle current limiting, and a latch for single pulse metering. The flexibility of this series allows it to be easily configured for either current mode or voltage mode control. Features - 50 ns Propagation Delay to Output - High Current Totem Pole Output - Wide Bandwidth Error Amplifier - Fully- Latched Logic with Double Pulse Suppression - Latching PWM for Cycle- By- Cycle Current Limiting - Soft- Start Control with Latched Overcurrent Reset - Input Undervoltage Lockout with Hysteresis - Low Startup Current (500 m A Typ) - Internally Trimmed Reference with Undervoltage Lockout - 90% Maximum Duty Cycle (Externally Adjustable) - Precision Trimmed Oscillator - Voltage or Current Mode Operation to 1.0 MHz - Functionally Similar to the UC3823 - These are Pb- Free Devices http://onsemi. 16 1 16 1 PDIP- 16 P SUFFIX CASE 648 SOIC- 16W DW SUFFIX CASE 751G MARKING DIAGRAMS 16 MC34023P AWLYYWWG MC33023DW AWLYYWWG = Assembly Location = Wafer...
