The IRU3037 controller IC is designed to provide a low-cost on-board DC-to-DC synchronous buck regulator converter application. With today's ASIC migration product requirements, such as low supply voltages of 1.8V and low, coupled with currents exceeding 3A, the legacy is simply too lossy to use a linear regulator when the input supply is 5V, or even in some cases, with 3.3V...

The purpose of the IRU3138 controller IC is to provide a low voltage tracking cost synchronous buck regulator for applications such as DDR memory and general purpose on-board DC-DC converters. Modern microprocessors combined with DDR memory require a high-speed bandwidth data bus that requires a specific bus termination voltage. This voltage will be tightly regulated, tracked to ...

The ISL6211 is a single output power controller that powers Transmeta's Crusoe™ CPU core. The ISL6211 includes a 5-bit digital-to-analog converter (DAC) that adjusts the core PWM output voltage from 0.6VDC to 1.75VDC. This DAC setting may change during operation. Special measures have been taken to allow such a transition to control the slew rate, in line with T...
