ISL8002AFRZ-T13

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8002AFRZ-T13 is a monolithic 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, allowing for the use of small inductors. The output voltage is adjustable from 600mV to 5.5V. Integrated low rDS(ON) MOSFETs maximize efficiency, while the PMOS high-side switch eliminates the need for a bootstrap capacitor. The component supports both PFM and PWM light-load modes and is housed in an 8-pin TDFN-EP package.
