DESCRIPTION
●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
