IRU3037 / IRU3037A
8-PIN SYNCHRONOUS PWM CONTROLLER FEATURES
Synchronous Controller in 8-Pin Package Operating with single 5V or 12V supply voltage Internal 200KHz Oscillator (400KHz for IRU3037A) Soft-Start Function Fixed Frequency Voltage Mode 500mA Peak Output Drive Capability Protects the output when control FET is shorted
DESCRIPTION
The IRU3037 controller IC is designed to provide a low cost synchronous Buck
regulator for on-board DC to DC converter applications.
With the migration of today’s ASIC products requiring low supply voltages such as 1.
8V and lower, together with currents in excess of 3A, traditional...
