Innovative 60V Synchronous Buck Controller Simplifies Power Supply Design

News

Intersil’s first 60V synchronous buck controller bypasses the intermediate step-down conversion stage traditionally employed in industrial applications. The ISL8117 synchronous step-down PWM controller’s low duty cycle (40ns minimum on time) enables the direct step-down conversion from 48V to a 1V point-of-load. This technical achievement allows designers to reduce system complexity and solution cost in industrial, factory automation, medical and communications infrastructure applications.

In high-voltage applications where a lower output voltage is required, designers have traditionally relied on modules that increase system cost, or two stage DC/DC solutions that increase solution footprint and complexity.

The ISL8117 uses valley current mode modulation with adaptive slope compensation to enable stable operation for a wide range of Vin and Vout combinations, with no external compensation required. Using its adjustable frequency up to 2MHz enables optimal costs, size and efficiency.
