ISL80019FRZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL80019FRZ-T7A is a synchronous step-down DC/DC converter manufactured by Renesas Electronics Corporation. It delivers up to 2A of continuous output current from an input supply ranging from 2.7V to 5.5V. The device utilizes peak current mode control architecture, enabling very low duty cycle operation and superior transient response. It operates at switching frequencies of either 1MHz or 2MHz, which allows for the use of small inductors. The converter integrates very low rDS(ON) MOSFETs to maximize efficiency and eliminates the need for a boot capacitor due to the PMOS high-side switch. It supports both PFM and PWM modes for light load optimization.
