Description
The S5U2596M series of regulators are monolithic integrated circuit
that provides all active functions for a step-down (buck) switching
regulator, capable of driving 3A load with excellent line and load
regulation. These devices are available in fixed output voltages of
3.3V,5V,12V and an adjustable output version. The S5U2596M
series ioerate at a switching frequency of 150 KHz; thus allowing
smaller sized filter components than what would be needed with
lower frequency switching regulators. Available in standard 5-lead
TO-263 package with several different lead bend options. Other
feature include a guaranteed ±4% to tolerance on output voltage
under specified input voltages and output load conditions. The 150
KHz ±15% is on the oscillator frequency. External shutdown is
included, featuring 80uA(Typ.) standby current. The output switch
includes cycle-by cycle current limiting, as well as thermal shutdown
for full protection under fault conditions.
