Short-circuit protection Reset output Power Fail programmable input Inhibit/Enable control input Soft-start PCB or chassis mounting DESCRIPTION The GS-R51212S and GS-R51515S are versatile triple output, high current step-down switching regulators that provide +5.1V/4.5A output voltage and an isolated ±12V/0.35A or ±15V/0.3A dual output voltage. They are ideal for microprocessor based boards because power the logic and the communication ports and have Reset output and Power Fail programmable input for the correct system start-up. ABSOLUTE MAXIMUM RATINGS Symbol Vi Irs DC Input Voltage Reset Output Sink Current Parameter Value 44 20 Unit V mA The Inhibit/Enable pin allows the ON/OFF logic function with TTL/CMOS compatible input signal. The auxiliary outputs (±12V or ±15V) are externally adjustable in a very wide range, i.e. from ±4.25V to ±12.45V on GS-R51212S and from ±4.50V to ±15.25V (typical values) on GS-R51515S.
