The ISL83385E is an Intersil-produced 3.0V to 5.5V powered RS-232 transmitter/receiver that meets EIA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. It is mainly used in PDAs, Palmtops and notebook and laptop computers that require low power consumption. The device employs an efficient on-chip charge pump and a manual power-down function to reduce standby supply current to 1µA. The small footprint packaging and the use of small, low-value capacitors also save board space. Under the worst-case load conditions, data rates greater than 250kbps are guaranteed. This device is fully compatible with 3.3V only systems, mixed 3.3V and 5.0V systems, and 5.0V only systems. The single-pin power-down function (SHDN = 0) disables all the transmitters, while shutting down the charge pump to minimize supply current drain. Table 1 summarizes the features of the ISL83385E, while Application Note AN9863 summarizes the features of each device comprising the 3V RS-232 family.

ISL8560MREP is Intersil's step down DC/DC power switching regulator, which accepts input voltage from 9.0V to 60V and provides 2A output current. The output voltage can be set in the range between 1.21V and 55V by means of an external divider. The device uses an internal power DMOS transistor with a typical rDS(ON) of 0.19Ω to obtain very high efficiency and high switching speed. A switching frequency in the range of 100kHz to 600kHz can be realized (the maximum power dissipation of the various packages must be observed). Notable features of this next generation of DC/DC converter includes pulse-by-pulse current limit for FET protection, hiccup mode for short circuit protection, voltage feedforward regulation, Frequency SYNC, soft-start, low standby current of 60µA typical in the disabled state, and thermal shut-down. The device is available in a 20 Ld QFN package.

ISL65426MREP is a high efficiency dual output monolithic synchronous buck converter operating over an input voltage range of 2.5V to 5.5V. This single chip power solution provides two output voltages which are selectable or externally adjustable from 1.2V to 80% of the supply voltage while delivering up to 6.0A of total combined output current when used at TJ of +125°C or less. The two PWMs are synchronized 180° out of phase reducing the RMS input current and ripple voltage. The ISL65426MREP switches at a fixed frequency of 1MHz and utilizes current-mode control with integrated compensation to minimize the size and number of external components. The internal synchronous power switches are optimized for good thermal performance, high efficiency, and eliminate the need for an external Schottky diode. A unique power block architecture allows partitioning to support one of four configuration options. One master power block is associated with each synchronous converter channel. Four floating slave power blocks allow the user to assign them to either channel. Proper external configuration of the power blocks is verified internally prior to soft-start initialization. Independent enable inputs allow for synchronization or sequencing soft-start intervals of the two converter channels. A third enable input allows additional sequencing for multi-input bias supply designs. Individual p
