Detailed Description for ISL85003AFRZ
Product Overview
The ISL85003AFRZ from Renesas Electronics Corporation is a surface-mount buck switching regulator with a positive adjustable output. It accepts input voltages from 4.5 V to 18 V and provides a single output adjustable from 0.8 V to 18 V at up to 3 A. The device uses a 500 kHz switching frequency, synchronous rectification, and a 12-VFDFN exposed-pad package.
Key Features
- Step-down buck regulator topology with one positive output
- Input voltage range of 4.5 V to 18 V
- Adjustable output voltage from 0.8 V to 18 V
- 3 A output current capability
- 500 kHz switching frequency with synchronous rectifier
- Surface-mount 12-VFDFN exposed-pad package
- Operating temperature range of -40°C to 125°C (TJ)
Applications
- Point-of-load voltage conversion for digital logic rails in embedded boards
- Adjustable intermediate supply rail generation in control and instrumentation systems
- Regulated 3 A power delivery from 4.5 V to 18 V DC input sources
Design & Procurement Notes
When selecting this regulator, match the 4.5 V to 18 V input range and the adjustable 0.8 V to 18 V output requirement to the system supply and load. The 3 A output and 500 kHz switching frequency should guide external power-stage component choices. The 12-VFDFN exposed-pad surface-mount package requires a compatible PCB footprint and pad layout, while the -40°C to 125°C (TJ) operating range should be considered in thermal and board-level design.
