Description:The P9243-GB is a highly integrated, magnetic induction, wireless power transmitter that supports up to 15W in compliance with the WPC-1.2.4 specification or proprietary applications. It is compatible with all popular wireless charging protocols including the WPC Baseline Power Profile (BPP), Extended Power Profile (EPP), up to 7.5W charging for iPhones, and Samsung Fast Charge. This system-on-chip solution (SoC) operates with an input voltage range of 5V to 19V.The P9243-GB transmitter IC includes an indus
Renesas provides a recommended PCB layout guide in their application note (APN) document, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
The P9243-GBNDGI has a built-in overcurrent protection feature, but it's recommended to add an external overcurrent protection circuit to ensure reliable operation. Renesas provides a reference design for overcurrent protection in their application note.
The recommended input capacitor value and type depend on the specific application and operating conditions. Renesas recommends using a low-ESR ceramic capacitor with a value between 4.7uF to 10uF, but it's essential to consult the application note for specific guidance.
Renesas provides EMC design guidelines in their application note, which include recommendations for PCB layout, component selection, and shielding to ensure EMC compliance. Additionally, it's essential to follow the relevant EMC standards and regulations for the target application.
The P9243-GBNDGI has an operating temperature range of -40°C to +125°C, but it's essential to consult the datasheet and application note for specific guidance on thermal management and derating.
