MC34023, MC33023
High Speed Single-Ended
PWM Controller
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.
reference undervoltage lockouts each with hysteresis, cycle−by−cycle
current limiting, and a latch for single pulse metering.
