ISL9103A	July 2009

500mA 2.4MHz Low I_Q High Efficiency Synchronous Buck Converter

The ISL9103, ISL9103A is a 500mA, 2.4MHz step-down regulator, which is ideal for powering low-voltage microprocessors in compact devices such as PDAs and cellular phones. It is optimized for generating low output voltages down to 0.8V. The supply voltage range is from 2.7V to 6V allowing the use of a single Li+ cell, three NiMH cells or a regulated 5V input. It has guaranteed minimum output current of 500mA. A high switching frequency of 2.4MHz pulse-width modulation (PWM) allows using small external components. Under light load condition, the device operates at low I_Q skip mode with typical 20μA quiescent current for highest light load efficiency to maximize battery life, and it automatically switches to fixed frequency PWM mode under heavy load condition.

ISL3178AE	May 2009

±15kV ESD Protected, 3.3V, Full Fail-Safe, Low Power, High Speed or Slew Rate Limited, RS-485/RS-422 Transceivers

The Intersil ISL3178AE is ±15kV IEC61000 ESD Protected, 3.3V-powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. This device has very low bus currents (+125mA/-100mA), which presents a true "1/8 unit load" to the RS-485 bus. This allows up to 256 transceivers on the network without violating the RS-485 specification's 32 unit load maximum, and without using repeaters. For example, in a remote utility meter reading system, individual meter readings are routed to a concentrator via an RS-485 network, so the high allowed node count minimizes the number of repeaters required.

ISL6265A	May 2009

Multi-Output Controller with Integrated MOSFET Drivers for AMD SVI Capable Mobile CPUs

The ISL6265A is a multi-output controller with embedded gate drivers. A single-phase controller powers the Northbridge (VDDNB) portion of the CPU. The two remaining controller channels can be configured for two-phase or individual single-phase outputs. For uniplane CPU applications, the ISL6265A is configured as a two-phase buck converter. This allows the controller to interleave channels to effectively double the output voltage ripple frequency, and thereby reduce output voltage ripple amplitude with fewer components, lower component cost, reduced power dissipation, and smaller area. For dual-plane processors, the ISL6265A can be configured as independent single-phase controllers powering VDD0 and VDD1. The heart of the ISL6265A is the patented R³ Technology™, Intersil's Robust Ripple Regulator modulator. Compared with the traditional buck regulator, the R³ Technology™ has a faster transient response. This is due to the R³ modulator commanding variable switching frequency during a load transient.
