ISL80030FRZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL80030FRZ-T7A is a monolithic synchronous step-down DC/DC converter delivering up to 3A continuous output current from a 2.7V to 5.5V input supply. It utilizes peak current mode control for low duty cycle operation and operates at switching frequencies of 1MHz or 2MHz. The device features integrated PMOS high-side and NMOS low-side MOSFETs, eliminating the need for a bootstrap capacitor. It supports 100% duty cycle operation and includes comprehensive protection mechanisms such as overcurrent, short-circuit, over-temperature, undervoltage lockout, and overvoltage protection.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'FRZ' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the exact temperature grade and packaging format required for your production line. Cross-reference with the latest datasheet revision to confirm availability status and any potential lifecycle changes before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for applications needing up to 3A output current from a single-cell lithium battery or USB source. The integrated PMOS driver simplifies the design by removing the bootstrap capacitor, reducing the external component count. Choose this part for systems prioritizing high efficiency and fast transient response under PWM control modes.

Voltage Regulators - DC DC Switching Regulators Part Context

The ISL80030 belongs to the ISL80030x/ISL80031x family of highly efficient synchronous buck converters. While the ISL80030 variants utilize PWM control for fast transient response, the companion ISL80031 variants use PFM for higher light-load efficiency. Both families share similar electrical characteristics, input voltage ranges, and physical packaging options within the 2mm x 2mm DFN footprint.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ISL80030A is a direct functional substitute within the same family, offering identical electrical performance and pinout compatibility. Verify that the replacement part number matches the required operating temperature range and packaging configuration to ensure seamless integration into existing designs.
