Overview
The DA9130-XXRT2-AT is a dual-phase, high-efficiency synchronous buck DC-DC converter manufactured by Renesas Electronics Corporation. It integrates power FETs to deliver up to 10A of output current per phase, supporting a wide input voltage range from 2.5V to 5.5V and an adjustable output voltage range from 0.3V to 1.9V. The device features a nominal switching frequency of 4MHz and includes programmable GPIOs for flexible system configuration. It operates within an ambient temperature range of -40°C to +105°C and utilizes a compact 24-pin FC-QFN package with wettable flanks.
Feature Summary
- Dual-phase architecture providing high current density and reduced thermal stress
- Integrated synchronous power FETs eliminating the need for external components
- I2C-compatible interface for dynamic voltage control and monitoring
- Programmable general-purpose I/Os for customized system integration
Applications
- High-performance processing systems requiring efficient power delivery
- Advanced Driver Assistance Systems (ADAS) in automotive applications
- Infotainment and telematics units
- Navigation systems demanding stable low-voltage rails
Procurement Notes
Verify the specific suffix 'AT' against official Renesas documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure compatibility with existing BOM constraints regarding the FC-QFN footprint. Confirm that the selected output voltage configuration aligns with the target load requirements before finalizing procurement orders.
Selection Notes
Select this component when designing systems that require high current capacity from a single IC without external power stages. Consider the 4MHz switching frequency for smaller passive component sizes. Evaluate the thermal performance benefits of the integrated FET design against discrete solutions. Ensure the I2C address settings do not conflict with other devices on the bus.
Part Context
This part belongs to the DA9130 series of sub-PMICs designed for automotive and industrial applications. It complements other Renesas power management solutions by offering scalable power delivery for complex digital loads. The series emphasizes reliability and efficiency in space-constrained environments.
Replacement Considerations
Consult official substitution lists for equivalent dual-channel buck converters. Verify pin-to-pin compatibility and electrical parameter alignment if considering alternative manufacturers.
