Sipex Announces the SP6121 PWM Controller

August 05, 2001 by Jeff Shepard

Sipex Corp. (Billerica, MA) announced the availability of its new SP6121 low-voltage, high-power dc/dc synchronous PWM controller. The SP6121 features a programmable output-voltage range of 1.25V to 7V with an output-current capability of up to 15A and efficiencies as high as 95 percent. Sipex reports that the device maintains its accuracy over a wide range of line, load and temperature conditions.

The SP6121 comes in an eight-lead narrow SOIC package and uses very few low-profile surface-mount components. It is suitable for use in board-level, distributed-power applications that require fast transient responses, such as DSPs, microprocessor cores, high-speed dynamic logic and digital ASICs. The SP6121 has a fixed frequency of 500 kHz. It is fully fault-protected and has on-board hiccup-mode current limit, output over-voltage protection, under-voltage lockout and loss-less adjustable current limit.

"The SP6121 completes our first family of PWM buck controllers, all introduced in the first half of this year" said Tim Goodrow, vice president of marketing for Sipex. "The SP6120 family provides our customers with a variety of single-supply dc/dc buck controllers with feature sets and price points that range from very simple, low-cost solutions to high-end, feature-rich, highly flexible solutions. Each of the products in the family share a common PWM core architecture, making the migration path from the simpler to the more complex controllers very straightforward for our customers."

The SP6121 is currently available for $1.05 each in 10,000-piece quantities.
