General Description

The US3036 IC provides an 8 pin low cost switching controller with true short circuit protection all in a pact 8 pin surface mount package, providing a low cost switching solution for applications that require a simple switching regulator from the 5V input where there is no other supply available.

One type of such application is generating 2.5V standby from the dual 5V(5V and 5V standby) for the next generation processors.

The IC starts below 4.5V supply and drives an external Pch MOSFET or and external low cost PNP as the switching element.

Key Features

  • 8 pin SOIC Switching Controller with HICCUP Current Limiting Reduces Diode Power Dissipation to Less than 1% of Normal Operation Soft Start Capacitor allows for smooth Output Voltage ramp up On board MOSFET driver Fastest transient response of any controller method. ( 0 to 100% Duty Cycle in 100 nS ) 1% internal voltage reference Internal Under Voltage Lockout protects MOSFET during start-up.
