Datasheet Summary
PWM SWITCHER & LINEAR CONTROLLER IC Features
LDO Controller allows the use of a low cost pass transistor for the I/O supply 8 pin SOIC bines switching and linear controller Internal Pre-regulator Eliminates Cross talk between Switching & Linear regulators Automatic shut down of the linear regulator when connected to the Vcc2 Det pin 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
DESCRIPTION
The US3033 IC bines a switching controller and a linear regulator controller all in a pact 8 pin surface mount package, providing...
