bipolar transistor is shown in the Figure 29. It is an ideal
solution for configurations where the input and output
voltage difference is small and high efficiency is required.
NSS35200,
ON Semiconductor will be ideal for applications with 1 A
output current, the input voltages up to 15 V and operating
frequency 100 − 150 kHz. The switching speed could be
improved by using desaturation diode D2.
