Semtech expands its power management portfolio

Newbury Park, California–Semtech Corp., a supplier of mixed-signal semiconductors for communications, computers, and industrial equipment, today announced a family of linear FET controllers that enable simple, space-saving design of distributed single and dual power supplies on primary and peripheral circuit boards.

The highly-integrated SC1538 (dual regulator) and SC1548 (single regulator) are linear voltage regulator controllers that together with inexpensive external N-channel FETs can be used to generate well-regulated output voltages with over-current protection, according to the company. The dropout voltage for an application can be met by selecting the required FET RDS(ON). Key applications include instantly-available PCs, next-generation computers, network hubs and routers, telecommunications systems and line cards, PC Cards, industrial PCs and DSP-based systems, among others.

“The SC1538 and SC1548 products expand Semtech’s portfolio of application-specific power management devices, strengthening our commitment to providing superior power solutions for system designers,” said Don Ashley, vice president of system power management products at Semtech. “These devices are indispensable for a whole host of applications, ranging from telecommunications and networking hardware, to computers, peripherals and industrial control systems.”
