The UC28023 and UC28025 are fixed-frequency PWM controllers optimized for high-frequency switched-mode power supply applications. The UC28023 is a single output PWM for single-ended
topologies while the UC28025 offers dual alternating outputs for double-ended and full bridge topologies.
FEATURES
Peak Current Mode, Average Current Mode, or Voltage Mode (with Feed-Forward) Control Methods
Practical Operation Up to 1 MHz
50-ns Propagation Delay to Output
±1.5-A Peak Totem Pole Outputs
9-V to 30-V Nominal Operational Voltage Range
Wide Bandwidth Error Amplifier
Fully Latched Logic with Double Pulse Suppression
Pulse-by-Pulse Current Limiting
Programmable Maximum Duty Cycle Control
Under--Voltage Lockout with Hysteresis
Trimmed 5.1-V Reference with UVLO
Same Functionality as UC3823 and UC3825
