ISL80030FRZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL80030FRZ-T is a monolithic synchronous buck converter from Renesas, delivering up to 3A continuous output current. It operates with an input voltage range of 2.7V to 5.5V and supports switching frequencies of 1MHz or 2MHz. The device features peak current mode control for low duty cycle operation and integrates low rDS(ON) PMOS and NMOS FETs. Key electrical parameters include a 35μA quiescent current, up to 95% peak efficiency, and internal soft-start/stop. Protection mechanisms cover overcurrent, short-circuit, over-temperature, undervoltage lockout, and overvoltage.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'FRZ-T' against the official datasheet to confirm tape-and-reel packaging and temperature grade. Ensure the ordering part number matches the exact pinout and thermal pad configuration required by your PCB layout. Cross-reference the manufacturer's latest revision history to confirm component availability and any potential form-fit-function changes before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring a compact, high-efficiency step-down solution with integrated FETs. The PWM control architecture makes it suitable for applications prioritizing fast transient response and low output ripple. Consider the 2x2mm DFN package for space-constrained designs where thermal performance via the exposed pad is critical for maintaining reliability under full load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL80030x/ISL80031x family of highly efficient synchronous DC/DC converters. While the ISL80031 variant utilizes PFM for light-load efficiency, the ISL80030 series specifically employs PWM for consistent performance. The family shares common protection features and control architectures but differs in modulation strategy to address distinct application requirements regarding noise and efficiency profiles.
