Product overview
Overview
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 linear regulators are simply too lossy to be used when input supply is 5V or even in some cases with 3.3V input supply.
The IRU3037 together with dual N-channel MOSFETs such as IRF7313, provide a low cost solution for such applications.
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
• SOIC 8-Lead also available LEAD-FREEAPPLICATIONS
• DDR memory source sink Vtt application
• Low cost on-board DC to DC such as 5V to 3.3V, 2.5V or 1.8V
• Graphic Card
• Hard Disk Drive
