Overview
The RT6258CHGQUF is an 8A synchronous step-down converter with integrated 3.3V and 5V LDOs, manufactured by Richtek USA Inc. It operates within a 5.1V to 23V input range and delivers up to 8A output current at 5V. The device features a fixed 750kHz switching frequency and 100uA quiescent current. Housed in a 12-UQFN-HL package (3x3mm), it supports surface mount installation and functions across a -40°C to +125°C junction temperature range.
Feature Summary
- Integrates a high-current synchronous buck converter with dual low-dropout regulators for combined power delivery.
- Utilizes UQFN-HL packaging to minimize board space while maintaining thermal performance.
- Supports wide input voltage ranges suitable for various industrial and consumer supply rails.
Applications
- Portable electronic devices requiring compact power solutions
- Industrial equipment needing reliable voltage regulation
- Consumer electronics utilizing multiple voltage domains
Procurement Notes
Verify the exact suffix CHGQUF against official Richtek documentation to confirm pinout and thermal pad configuration. Ensure compatibility with moisture sensitivity level requirements during assembly. Cross-reference datasheet revision dates to validate electrical characteristics before integration into final designs.
Selection Notes
Select this component when an 8A buck converter is required alongside fixed 3.3V and 5V auxiliary supplies. Consider the 750kHz frequency for balancing efficiency and passive component size. Evaluate thermal dissipation capabilities within the 12-UQFN-HL package relative to ambient conditions.
Part Context
This part belongs to the RT6258 family of PMICs from Richtek, designed for applications requiring integrated power management. It complements other variants like the RT6256 series which offer lower current ratings. The UQFN-HL package is common across several Richtek high-density power solutions.
Replacement Considerations
RT6258CGQUF is listed as an alias or alternative variant within the same product family, offering similar functionality but potentially different internal configurations or packaging details. Verify specific electrical parameters before substitution.
