Series
The UC2577-ADJ device provides all the active functions neces-
sary to implement step-up (boost), flyback, and forward converter
switching regulators. Requiring only a few components, these sim-
ple regulators efficiently provide up to 60V as a step-up regulator,
and even higher voltages as a flyback or forward converter regula-
tor.
The UC2577-ADJ features a wide input voltage range of 3.0V to
40V and an adjustable output voltage. An on-chip 3.0A NPN switch
is included with undervoltage lockout, thermal protection circuitry,
and current limiting, as well as soft start mode operation to reduce
current during startup. Other features include a 52kHz fixed fre-
quency on-chip oscillator with no external components and current
mode control for better line and load regulation.
A standard series of inductors and capacitors are available from
several manufacturers optimized for use with these regulators and
are listed in this data sheet.
