MILPITAS, CA--(Marketwired - Sep 10, 2013) - Intersil Corporation (NASDAQ: ISIL), a leading provider of innovative power management and precision analog solutions, today introduced the ISL85415, a versatile 500mA synchronous buck regulator featuring a wide input voltage range, integrated synchronous FETs and internal compensation.

New generations of communication, industrial and consumer systems require switching regulators to accommodate a wide range of input voltages and the ISL85415 meets that need supporting from 3V to 36V capability. An extended output voltage range of 0.6V to 95% of Vin also provides an excellent solution when enabling pulse-frequency modulation (PFM), a mode widely used in portable applications to improve efficiency at light loads.

The ISL85415 integrates both high-side and low-side NMOS FETs, eliminating the need for external FETs and diodes. This high level of integration reduces component count in standard buck configurations, simplifies the design process and saves time. Designers can also select external compensation if required. The wide Vin and Vout ranges, combined with integrated synchronous FETs and internal compensation, enable efficient, robust designs with a minimum number of external components.

Features and Specifications

  • Light load efficiency mode maximizes performance in low load conditions
  • Fixed 500KHz switching frequency or adjustable 300KHz to 2MHz provides flexible inductor choices
  • Quiescent current only 80uA -- excellent choice for battery-powered applications
  • Easy to design with using Intersil's iSim™ and online design/layout files

Pricing and Availability

The ISL85415 is available now in 4mm x 3mm DFN packaging with prices starting at $1.45 each in 1,000-piece units. Also available is a full-featured design evaluation kit (ISL85415EVAL1Z) and low-cost demo board (ISL85415DEMO1Z) priced at $72,00 and $20.00 respectively, and simulation capability within the Intersil iSim™ design simulation tool.
