Voltage Regulators - DC DC Switching Regulators datasheet and documents for MT6315GP/B

MT6315GP/B

Voltage Regulators - DC DC Switching Regulators Overview

The MediaTek MT6315GP/B is a specialized Power Management IC (PMIC) designed as a four-phase step-down buck converter. It provides four independent positive output channels, each capable of delivering up to 5A of current. The device supports programmable output voltages ranging from 0.4V to 1.19375V. It operates with an input voltage range between 540 mV and 6V. The component is available in a compact 45-pin WLCSP or 48-pin QFN package and functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Four-phase buck converter topology for high-current delivery
Programmable output voltage control
Compact wafer-level chip scale packaging
Extended industrial operating temperature range

Voltage Regulators - DC DC Switching Regulators Applications

Powering GPU rails on MediaTek Dimensity boards
Supplying processor-little core power
Providing SRAM and audio rail power

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific package variant (WLCSP vs. QFN) against the schematic, as both exist for this part number family. Confirm the suffix 'B' matches the required revision level for the target Genio 1200 or Dimensity platform. Ensure compatibility with the 0.4V minimum output requirement if powering sensitive logic cores.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this PMIC when designing for MediaTek SoCs requiring dedicated high-current buck regulation for CPU, GPU, or memory subsystems. The four-channel configuration allows simultaneous power distribution to multiple critical domains without external multiplexing. Consider thermal dissipation requirements given the 5A per phase capability in small form factors.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to MediaTek's specialized PMIC lineup for mobile and IoT processors. It serves as a critical power stage for high-performance computing blocks within System-on-Chip architectures. The MT6315 series is specifically engineered to meet the dynamic load transient requirements of modern digital logic cores.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires matching the pinout, electrical specifications, and software configuration registers of the original MediaTek design.
