Semtech's Software-Controlled Power Management IC Combines Five Programmable Regulators in One Small PackageWell suited for low-power portable applications, the highly integrated SC900 reduces parts inventory conserving board space and design time Camarillo, California - July 19, 2005 Semtech Corp. (NASDAQ: SMTC), a leading supplier of analog and mixed-signal semiconductors for communications, portable devices, computers, and industrial equipment, today announced the SC900, an I2C software-controlled power management device incorporating five individual, ultra-low dropout (ULDO) regulators in a tiny 4mm x 4mm package.
Designers will find the SC900 ideal for cellular phones, PDAs, personal media players, palmtop/laptop computers, and similar portable equipment. In these battery-powered devices it is essential that performance be maintained as the battery voltage slowly declines. This product delivers full performance on all five ULDOs over the input range of 2.7V to 5.5V. All five ULDOs are I2C programmable in 50mV increments from 1.45V to 3.00V with an accuracy of ±3 percent, and each LDO can be independently enabled/disabled. Output noise is 45µV (RMS), power supply rejection ratio is 60dB at 50mA, and current drawn in sleep mode is approximately 215uA for all five ULDOs in total operation. Device PCB footprint is approximately 4mm x 4mm assuring that the SC900 will make multi-ULDO layout more straightforward. "The SC900’s I2C interface allows for last minute adjustments to the five key power parameters to optimize system performance. Hardware designers can also focus on cost reduction via integration rather than individual device selection and qualification" says C.S. Mitter, Semtech's Director of Power Management for Handheld Products. The SC900 provides protection circuitry that prevents the device from operating in an unspecified state. These include undervoltage lockout protection, over-temperature protection, and short circuit protection. Key Features of the SC900

The SC900 adds the flexibility of I2C bus control so designers can quickly modify up to five common use, low dropout regulator requirements often present in battery-operated designs. Critical operational parameters can be changed or reset without replacing individual ULDOs or interface circuitry. These parameters include reset logic, power good indication, output voltage and active shutdown.
