YB1693  
2A / 150KHz Buck DC-DC Converter  
Description  
Features  
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  
devices are available in fixed output  
voltages of 3.3V, 5V and an adjustable  
output version.

Output Voltage: 3.3V, 5V & Adjustable  
version  
Adjustable Output Voltage Range  
1.23V~19.5V ±4%  
150KHz ±15% fixed switching  
frequency  
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 70μA (typical) standby current.  
The output switch includes cycle-by-cycle  
current limiting, as well as thermal  
shutdown for full protection under fault  
conditions.
