Diodes Incorporated has introduced a three-chip solution that enhances the performance of ultra-high power density USB Type-C power delivery (PD) systems. The solution products can be applied to a variety of consumer electronic product applications such as smart phone chargers and notebook computer transformers.

     Diodes Incorporated has introduced a three-chip solution that enhances the performance of ultra-high power density USB Type-C power delivery (PD) systems. The solution products can be applied to a variety of consumer electronic product applications such as smart phone chargers and notebook computer transformers.

 

     The AP43771V USB Type-C PD decoder is compatible with multiple communication protocols such as PD3.0, PPS Rev 3.0, V1.2 (TID – 4305) and Qualcomm® Quick Charge™ QC4/QC4+/QC5 (QC20201127203). This product supports 3.3V to 24V operating voltage, and can be used with all main firmware's single-write (OTP) ROM and multiple-write (MTP) ROM to store user-set data.

 

     In charging state, AP43771V can support various intelligent power management systems through I2C and GPIO pins and built-in application firmware, such as intelligent power sharing among multiple charging ports, thermal power derating, LED light indication and fault indication, etc.

 

     The AP3306 is an active clamp flyback (ACF) controller with zero voltage switching (ZVS) and magnetic energy recovery for better operating efficiency. This product can be used with an integrated driver GaN FET, a Cascode GaN FET, or a MOSFET as a low-side primary switch. The AP3306 integrates the high-side AFC gate driver control function and utilizes the high-side MOS switch with limited current capability to form a leakage energy recovery circuit. This highly integrated and cost-effective component can effectively reduce the total bill of materials (BOM) cost and save board space.

 

     The APR340 is a secondary-side synchronous rectification (SR) MOSFET driver optimized for use with the AP3306. This product has a built-in pulse linear regulator and operates in constant current (CC) mode to protect the charging system. The system can output a minimum voltage of 2V, which is of great help in the product application of Programmable Power Supply (PPS).

 

     The AP43771V is available in W-DFN3030-14 and W-QFN4040-24 packages. The package type of AP3306 is SO-10, and the package type of APR340 is SOT26
