Product Details
Product Details:

- Part Number: MT6308MP

- Sibling Variants: MT6308HP, MT6308P

- Manufacturer: MediaTek Inc. (MTK)

- Function: Envelope Tracking (ET) PMIC / Average Power Tracking (APT) DC-DC Converter for RF PA

- Application Section: RF Power Amplifier Modulated Power Supply (VPA / ET Rail)

- Bus Communication: High-speed SPMI / I2C interface integrated with Baseband/Modem

- Safety Features: Over-Voltage Protection (OVP), Over-Current Protection (OCP), Thermal Shutdown

- Package Type: Fine-Pitch BGA / WLCSP (Wafer-Level Chip Scale Package)

- Mounting Type: Surface Mount Technology (SMD BGA Soldering / Reballing)

Usage:

- Dynamic RF Voltage Modulation: Continuously adjusts the supply voltage rail (VPA) feeding 4G/5G power amplifiers based on transmit signal requirements, reducing power amplifier heat and battery consumption.

- Compatible Platforms & Devices:

* Samsung: Galaxy A14 5G (SM-A146P), Galaxy A22 5G (MediaTek MT6833 Dimensity 700 series)

* Xiaomi / Redmi / POCO: Redmi Note 10 5G, Redmi Note 9T / Note 9 5G, POCO M3 Pro 5G, Redmi Note 11 (MTK), Redmi K40S

* Infinix / Tecno: Infinix Note 12 5G / Zero 5G series, Tecno Camon 5G series

* Honor / Huawei: Honor X30i, X20 SE, Play 30 Plus, Honor 50 SE

- Common Fault Symptoms & Motherboard Diagnostics:

* Network & Signal Failure: "No Service", "Emergency Calls Only", weak reception, or inability to latch onto 5G/4G bands caused by zero or unstable output voltage on the PA rail.

* Overheating in RF Shield Section: Extreme heating around the RF section during phone calls or cellular data sessions due to internal shorting of the converter.

* Secondary Rail Short / High DC Leakage: A short circuit across the input supply or output buck coil pulls down primary power lines, creating a dead-phone or high DC supply current pulse.

* Dead After Flash / Recovery Failure: System fails to complete boot sequence if modem firmware checks cannot establish hardware handshake with the MT6308 chip.

* Diagnostic Caution: Not a main system PMIC or charging IC; replacing MT6308MP will not resolve USB charging or display backlight problems.
