YB1693

YB1693 Series are step-down switching regulators with all required active functions. It is capable of driving 2A load with excellent line and load regulations. These YB1693 devices are available in fixed output voltages of 3.3V, 5V and an adjustable output version.

YB1693 series operates at a switching frequency of 150KHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. It substantially not only reduces the area of board size but also the size of heat sink, and in some cases no heat sink is required. The ±4% tolerance on output voltage within specified input voltages and output load conditions is guaranteed. Also, the oscillator frequency accuracy is within ±10%. External shutdown is included. Featuring 70A (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
