Sipex Feature-Rich Wide Input Range Synchronous Buck Controllers Convert 22V Directly to 0.8V in a Single Step

07.09.2006 14:30 - Source: Sipex
(September 7, 2006) (OTC: SIPX.PK), - Sipex Corporation today announced two new single-rail synchronous buck controllers, the SP6133 and SP6136. With an integrated 5V LDO bias, the SP6133 and SP6136 are designed to drive a pair of external N-Channel FETs switching at 300kHz (SP6133) and 600kHz (SP6136) frequencies from a single voltage rail for point of load applications. These devices have a wide input voltage range from 4.5V to 24V with duty cycles down to 3.5%, enabling direct conversion from high input voltage to low output voltages in a single step, eliminating the need for intermediate bus conversion.

The SP6133 / SP6136 give the designer a unique combination of features:

  • Programmable start-up UVLO sets the minimum input voltage for safe operation
  • Internal VCC UVLO ensures the controller has sufficient voltage to properly operate
  • PWRGD output with adjustable delay indicates when the output voltage is in regulation eliminating the need for additional supervisory circuits
  • Hiccup-mode restart implemented into lossless current sense, thermal shutdown, and short circuit protection features
  • High-current gate drivers enable output currents up to 30A

    "Sipex is committed to expanding its portfolio to meet customer needs by launching our first single-rail PWM controllers providing high flexibility and multiple protection features," said Jules Farago, Senior Technical Marketing Manager. "These feature-rich ICs are the first in the family of single-rail PWM controllers from Sipex. They provide sequencing and tracking solutions to meet requirements demanded by today's system designers."

    Pricing and Availability

    The SP6133 and SP6136 are available in small 3x3mm QFN16 packaging, in an extended temperature range from -40°C to +85°C. Pricing is $1.50 in 1K units. Datasheets and additional support documentation can be found at www.sipex.com.
