The MC34025P is a high-speed, fixed-frequency, double-ended pulse width modulator controller designed for optimized high-frequency operation. It is particularly suited for Off-Line and DC-to-DC converter applications, offering a cost-effective solution with minimal external components. This integrated circuit includes an oscillator, a temperature-compensated reference, a wide bandwidth error amplifier, a high-speed current-sensing comparator, a steering flip-flop, and dual high-current totem-pole outputs ideal for driving power MOSFETs.
Key features include a fast 50 ns propagation delay to outputs, dual high-current totem-pole outputs, and a wide bandwidth error amplifier. It also incorporates fully-latched logic with double pulse suppression and latching PWM for cycle-by-cycle current limiting. The device supports soft-start control with latched overcurrent reset, input undervoltage lockout with hysteresis, and operates at frequencies up to 1.0 MHz. The maximum duty cycle is externally adjustable to 45%.
The MC34025P is available in PDIP-16 and SO-16WB packages. It is functionally similar to the UC3825 and is Pb-Free, Halogen Free/BFR Free, and RoHS Compliant. The device operates with a power supply voltage up to 30V and an output driver supply voltage up to 25V, featuring a typical 5.1V reference voltage.
