LM3485 Hysteretic PFET Buck Controller

The LM3485 is a high efficiency PFET switching regulator controller that a system designer can use to quickly and easily develop a small, low cost, switching buck regulator for a wide range of applications. The use of a hysteretic control scheme provides for simple design without any control loop st.
