S5J2596M
150 KHz, 3A PWM
Step-Down DC/DC Converter
Description
The S5J2596M 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 S5J2596M
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-252 package. Other feature include a guaranteed ± 4% to
tolerance on output voltage under specified input voltages and
output load conditions. The 150KHz ^±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.
