HI-SPD PWM Controller
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 components. These
integrated circuits feature an oscillator, a temperature compensated
reference, a wide bandwidth error amplifier, a high speed current
sensing comparator, 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. 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 Start–Up Current (500 μA 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 UC3823Vref
