DESCRIPTION
At the same time higher output currents are required and superior load transient performance has to be supplied due to very high dI/dt requests. A complete system solution is given and described. A connector with a standard VRM pinout is used, with 4 bit for Voltage Identify system, Power Good, Enable and constant limiting current functions are available. Output Over Voltage Protection is also available.
