Intersil Holding Debuts the IPM6220 Power-Management IC Chip Set

August 06, 2000 by Jeff Shepard

Intersil Holding Corp. (Irvine, CA) has introduced the first device from its family of power-management ICs targeted at next-generation, high-performance mobile products. The company claims that the IPM6220 chip set will increase battery life in compact wireless and mobile products by regulating system energy usage.

The Intersil chip set design allows the CPU voltage regulator to be turned off when the microprocessor is not in use. This option eliminates voltage generation for the CPU and, according to Intersil, reduces total system power consumption. The device automatically adjusts PWM outputs to meet reduced current requirements in lower power sleep states, and these outputs can be individually turned off to reduce power consumption further.

According to Intersil, the device boosts efficiency by eliminating current sense resistors and by using the resistance of the lower MOSFETs. Intersil's MOSFET and controller IC products have been designed to work together to combat thermal challenges of new microprocessors and peripherals. The IC device is highly integrated and provides power control and protection for the five output voltages (+12V, 5V, 3.3V, 5V standby and 3.3V standby) that typical notebook PCs require.

The IPM6220 will be available in a 24-pin SSOP package. Samples, evaluation boards, reference designs and application notes are currently available and cost $3.50 each in quantities of 1,000.
