US3036 - UNISEM

US3036 8 PIN PWM SWITCHER CONTROLLER IC

The US3036 IC provides an 8 pin low cost switching controller with true short circuit protection all in a compact 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 fr.
