High Speed Double-Ended PWM Controller
ORDERING INFORMATION -
The MC34025 series are high speed, fixed frequency, double–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, steering flip–flop, and dual high
current totem pole outputs ideally suited for driving power MOSFETs.
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 Outputs Dual High Current Totem Pole Outputs 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 UC3825
