FEATURES  
DESCRIPTION  
D
Peak Current Mode, Average Current Mode,  
or Voltage Mode (with Feed-Forward) Control  
Methods  
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.

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  
Targeted for cost effective solutions with minimal  
external components, UC2802x include an  
oscillator, a temperature compensated reference,  
a wide band width error amplifier, a high-speed  
current-sense comparator and high-current  
active-high totem-pole outputs to directly drive  
external MOSFETs.

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  
Protection circuitry includes a current limit  
comparator with a 1-V threshold, a TTL  
compatible shutdown port, and a soft-start pin  
which will double as a maximum duty cycle clamp.  
The logic is fully latched to provide jitter free  
operation and prohibit multiple pulses at an  
output. An undervoltage lockout section with  
800 mV of hysteresis assures low start-up  
current. During undervoltage lockout, the outputs  
are high impedance. Particular care was given to  
minimizing propagation delays through the  
comparators and logic circuitry while maximizing  
bandwidth and slew rate of the error amplifier.  
APPLICATIONS  
D
Off-Line and DC/DC Power Supplies  
D
Converters Using Voltage Mode, Peak  
Current Mode, or Average Current Mode  
Control Methods  
D
Single-Ended or Two-Switch Topology  
Designs  
Devices are available in the industrial temperature  
range of −40°C to 105°C. Package offerings are  
16-pin SOICW (DW), or 16-pin PDIP (N)  
packages.
