G5U2596M

150 KHz, 3A PWM Step-Down DC/DC Converter

Description

The G5U2596M 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 G5U2596M series operate 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 a standard 5-lead TO-263 surface mount

package. 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.
