ISL68134IRAZ-TR5845

Power Supply Controllers, Monitors Overview

The ISL68134IRAZ-TR5845 is a digital dual-output, flexible multiphase PWM controller from Renesas Electronics. It supports Adaptive Voltage Scaling (AVSBus) and allows either output to serve as the primary or secondary phase. The device operates within a supply voltage range of 3.135V to 3.465V and draws a typical supply current of 63 mA. Designed for surface mount assembly, it is housed in a 40-WFQFN exposed pad package with dimensions of 5x5 mm. The component functions across an operating temperature range of -40°C to +85°C.
