com LM3743 N-Channel FET Synchronous Buck Controller for Low Output Voltages September 2006 LM3743 N-Channel FET Synchronous Buck Controller for Low Output Voltages General Description The LM3743 is a voltage mode PWM buck controller which implements synchronous rectification.
It provides a low cost, fault tolerant, and efficient point of load solution.
To reduce component count several parameters are fixed, such as switching frequency and the short circuit protection level.
For example the LM3743 has an operating switching frequency of 300 kHz or 1 MHz and a fixed 500 mV high side current limit for switch node short-circuit protection.
LM3743 is a very fault tolerant IC w...
