The UC1825 family of PWM control ICs is optimized for high frequency switched mode power supply applications. These controllers are compatible with voltage or current mode topologies and feature high speed operation, low propagation delay, and high current dual totem pole outputs.
Key Features:
High Speed Operation: 1MHz switching frequency, 5ns propagation delay to output, and 80ns rise/fall time.
Protection Circuitry: Current limit comparator, TTL compatible shutdown port, and under-voltage lockout with hysteresis.
Error Amplifier: Wide bandwidth, high slew rate, and low output noise.
Output Stage: High current dual totem pole outputs with low output impedance.
Applications:
These controllers are suitable for high speed PWM applications, including current-mode and voltage-mode switched mode power supplies.
