Overview
The RAA230409GFT#YK0 is a quad-output power management IC (PMIC) manufactured by Renesas Electronics Corporation. It integrates three synchronous buck converters and one low-dropout regulator (LDO). The device operates with an input voltage range of 2.5V to 5.5V and features switching frequencies between 1.3MHz and 2.2MHz. Output specifications include adjustable voltages from 0.9V to 4.95V with current ratings of 500mA, 100mA, and 1.5A for the buck channels. It is housed in a 32-TQFP package with dimensions of 7x7mm.
Feature Summary
- Integrates three synchronous buck regulators and one LDO within a single component
- Supports wide input voltage ranges suitable for various system power rails
- Features high-frequency switching operation to minimize external passive component size
Applications
- Portable electronic devices requiring multi-rail power distribution
- Embedded systems utilizing mixed-signal processing units
- Industrial control modules needing compact power solutions
Procurement Notes
Verify the specific suffix #YK0 against official Renesas documentation to confirm exact packaging or tape-and-reel specifications. Confirm availability status as this series may have end-of-life notifications. Ensure compatibility with existing PCB footprints for the 32-TQFP package before procurement.
Selection Notes
Select this component when a compact solution for multiple regulated outputs is required. Consider the thermal performance of the 32-TQFP package under maximum load conditions. Verify that the integrated switching frequency aligns with electromagnetic interference requirements of the target application.
Part Context
This part belongs to the RAA23040x family of PMICs designed for space-constrained applications. It serves as a consolidated power solution replacing discrete regulator arrangements. The family targets efficiency improvements through synchronous rectification technology.
Replacement Considerations
Consult official cross-reference lists for direct replacements. Verify pin-to-pin compatibility and electrical parameter equivalence if substituting with other PMIC families.
