LM3743 N-Channel FET Synchronous Buck Controller

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 e.
