Elantec Semiconductor Introduces Two New 4-Amp Monopower ™ DC:DC Converters
The EL7563C and EL7564C with output voltages down to +1.0V offer 95% efficiency and 4-Amp output in a small SOL20 package
MILPITAS, CALIFORNIA, December 5, 2000 -- Elantec Semiconductor, Inc. (NASDAQ: ELNT), a leader in high-performance analog integrated circuits, today introduced two new 4-Amp single chip synchronous buck DC:DC converters with integrated power transistors (FETs). The EL7563C and the EL7564C target applications in the communications, graphics, and PC markets that require high-density, small form factor ASIC logic boards, lower operating voltages, smaller PCB space, and higher efficiency power supply designs.
Elantec's EL7563C and EL7564C operate from an input voltage range of +3.0V to +3.6V and +4.5 to +5.5V, respectively. Both products are capable of delivering a current of 4-Amps at up to 95% efficiency over the full industrial temperature range of -40 degrees C to +85 degrees C. The EL7563C and EL7564C integrate the pulse width modulator (PWM), control logic, a precision reference, and two continuous 4-Amp MOSFETs (transistors) in a 20-pin fuse-lead SOL package. Power system reliability and monitoring are enhanced by features such as: our patented on-chip resistorless current sensing which provides cycle-by-cycle current limiting, over-current protection, and excellent step load response; over temperature protection via an on-chip sensor for supervisor monitoring or automatic thermal shutdown; and over/under voltage protection for monitoring or for automatic disable of the output.
Power tracking makes the start-up sequencing of multiple converters possible and power sharing enables the use of these converters in parallel to provide more than 4-Amps of output current. Internal soft-start protects the central processing unit (CPU) from initial power-on voltage transients and reduces in-rush current. In addition, PWM oscillator frequency can be set with a single external capacitor or synchronized with an external clock to prevent interference in the total power-supply system design.
Steve Sacarisen, Elantec's Director of Strategic Marketing for Power Products said, "The integration of the two MOSFETs reduces total system component count, saves board space, and decreases electromagnetic interference (EMI) while increasing efficiency and enhancing reliability. Our fully integrated DC:DC converters offer our customers a very high-efficiency, low-cost power system solution."
The price for the EL7563C and EL7564C in the 20-pin SOL package in 1,000-piece quantities is $3.63 each. Samples are available now, with delivery of production quantities in 6 weeks.
