1 / 21 page  IRU3073 1 Rev. 1.0 09/17/03 www.irf.com DESCRIPTION The IRU3073 controller IC is designed to provide a low cost synchronous Buck regulator for on-board DC to DC converter for multiple output applications. The outputs can be programmed as low as 0.8V for low voltage applications. Selectable over-current protection is provided by using external MOSFET's on-resistance for optimum cost and performance. This device features a programmable frequency set from 200KHz to 400KHz, under-voltage lockout for all input supplies, an external programmable soft-start function as well as output under-voltage detection that latches off the device when an output short is detected. Synchronous Controller plus one LDO controller Current Limit using MOSFET Sensing Single 5V/12V Supply Operation Programmable Switching Frequency up to 400KHz Soft-Start Function Fixed Frequency Voltage Mode Precision Reference Voltage Available Uncommitted Error Amplifier available for DDR voltage tracking application PACKAGE ORDER INFORMATION FEATURES SYNCHRONOUS PWM CONTROLLER WITH OVER-CURRENT PROTECTION / LDO CONTROLLER APPLICATIONS DDR memory source sink VTT application Low cost on-board DC to DC such as 12V/5V to output voltages as low as 0.8V Graphic Card Hard Disk Drive Multi-Output Applications TA (°C) DEVICE PACKAGE 0 To 70 IRU3073CQ 16-Pin Plastic QSOP NB (Q) Data Sheet No. PD94699 Figure 1 - Typical application of IRU3073.
