CXSD6257 300KHz fixed frequency PWM buck (step-down) DC/DC converter 4A load with high efficiency Wide 5V to 32V Input Voltage Range
CXSD6257 The PWM control circuit is able to adjust the duty ratio linearly from 0 to
100%. An enable function, an over current protection function is built inside.
When short protection function happens, the operation frequency will be
reduced from 300KHz to 60KHz
