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.
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.
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.
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.
