Improved Replacement for LM2577 Series
The TL3577 series are easy-to-use devices that incorporate all the active circuitry required to implement either
step-up (boost), flyback, forward converter, or SEPIC converter switching regulators. The internal 3-A 65-V
switch allows the TL3577 to provide an output voltage of up to 60 V as a simple boost regulator; higher output
voltages can be achieved with the TL3577 configured as a flyback or forward converter.
Requiring few external components, The TL3577 features a wide input voltage range of 3 V to 40 V and offers
an adjustable output voltage. Basic protection features include undervoltage lockout, thermal protection, and soft
start, which is provided to reduce input current during startup. Current-mode control provides cycle-by-cycle
current limiting, as well as faster line and load regulation. The internal 100-kHz oscillator allows for use of
smaller magnetics and filter components, when compared with similar regulators running at 52 kHz. A standard
series of inductors and capacitors optimized for use with these regulators is available from several
manufacturers and are listed in this data sheet.
The TL3577 is characterized for operation over the virtual junction temperature range of –40
°C to 125°C.
