Improved power supply regulation for LCD-based PCs

26 September 2001 Power Electronics / Power Management

Intersil has extended its Endura range of power management solutions for PCs, file servers and portable appliances with a new system power regulator IC specifically optimised for PCs using liquid crystal displays. Featuring a power efficiency of 97%, the ISL6235 provides integrated power control and protection with five output voltages for high-efficiency power control in high-performance desktop or notebook PCs and PDAs with LCD screens.

The Endura ISL6235 offers the highest level of integration in the industry. It integrates three pulse width modulator (PWM) controllers and two linear regulators into a single 24-pin SSOP package to provide five regulated voltages required for the CPU, peripheral circuitry and LCD display, with full monitoring and protection. PCs using LCD displays are often only powered from an AC/DC wall adapter providing between 16 and 20 V. The ISL6235 accommodates this high voltage input by operating directly from DC voltages from 5,6 to 24 V and converts this to the system voltages required by the PC and display. It efficiently regulates all CPU and system electronics energy usage and delivers a highly integrated, multiple-output solution.

Additionally, the device enables lower-cost N-channel metal-oxide semiconductor field effect transistors (MOSFETs) to be used in place of P-channel MOSFETs, further lowering the cost of the entire system while reducing the physical size of power control circuitry. It is available in 24-lead SSOP package.
