It operates from 5V to 14V input voltage range, and provides up to 2A continuous output current with the output voltage adjustable down to 0.8V. Whenever the load is light, the G5632 automatically change the PWM operation mode to PFM operation to minimize the power consumption. Hence it is suitable for battery-powered devices. The G5632 is available in a SOP-8 package. Ordering Information ORDER NUMBER MARKING G5632P11U G5632 Note: P1:SOP-8 1: Bonding Code U: Tape & Reel TEMP.
