REGULATING PULSE WIDTH MODULATORS
• 8-V to 35-V Operation
• 5.1-V Reference Trimmed to 1%
The UC1525A/1527A series of pulse width modulator
integrated circuits are designed to offer improved
• 100-Hz to 500-kHz Oscillator Range
performance and lowered external parts count when
• Separate Oscillator Sync Terminal
used in designing all types of switching power
• Adjustable Deadtime Control
supplies. The on-chip +5.1-V reference is trimmed to
1% and the input common-mode range of the error
• Internal Soft-Start
amplifier includes the reference voltage, eliminating
• Pulse-by-Pulse Shutdown
external resistors. A sync input to the oscillator allows
• Input Undervoltage Lockout With Hysteresis
multiple units to be slaved or a single unit to be
synchronized to an external system clock. A single
• Latching PWM to Prevent Multiple Pulses
resistor between the CT and the discharge terminals
• Dual Source/Sink Output Drivers
provides a wide range of dead-time adjustment.
These devices also feature built-in soft-start circuitry
with only an external timing capacitor required. A
shutdown terminal controls both the soft-start circuitry
and the output stages, providing instantaneous turn
off through the PWM latch with pulsed shutdown, as
well as soft-start recycle with longer shutdown
commands.
