2.3.2 TPS562202

The TPS562202 is a simple, easy-to-use, 2-A synchronous buck converter in a SOT563 package. The device is optimized to operate with minimum external components and also optimized to achieve low standby current. Its input range up to 17 V covers most laboratory supply options. The switching frequency of 580 kHz does not interfere with the frequency band for arc detection.
