Renesas ISL81601

Overview

Topology	Buck-Boost Converter
Input voltage	32-60 V
Switching frequency	100-600 kHz
Output 1	48 V / 10 A
IC revision	0.00

Description

The ISL81601DEMO1Z demonstration board (shown in Figure 8 on page 9) features the ISL81601, a 60V high voltage synchronous buck-boost controller that offers external soft-start, independent enable functions, and integrates UV/OV/OC/OT protection. Programmable switching frequency ranging from 100kHz to 600kHz helps to optimize inductor size while the strong gate driver delivers up to 20A for the buck-boost output.

Features

Wide input range: 32V to 60V
Bidirectional operation
High light-load efficiency in pulse skipping DEM operation
Programmable soft-start
Optional DEM/PWM operation
Optional CC/HICCUP OCP protection
Supports prebias output with soft-start
PGOOD indicator
OVP, OTP, and UVP protection
Parallelable operation
