Diodes’s overall solution for ultra-high power density chargers has the advantages of higher efficiency and space saving products

Diodes Corporation recently launched a three-chip solution that can increase ultra-high power density USB Type-C^® The performance of the power delivery (PD) system. The solution products can be applied to a variety of consumer Electronic product applications such as smart phone chargers and laptop transformers.

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

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

AP3306 is an active clamp flyback (ACF) controller that achieves better operating efficiency through zero voltage switching (ZVS) and magnetic energy recovery. This product can be used with an integrated driver GaN FET, a Cascode GaN FET or a MOSFET as the main low-side switch. AP3306 integrates the high-side AFC gate driver control function, and uses 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 material (BOM) cost and save board space.

APR340 is a secondary-side synchronous rectification (SR) MOSFET driver, optimized for use with 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 to the application of programmable power supply (PPS) products.

AP43771V offers two package types, W-DFN3030-14 and W-QFN4040-24. The package type of AP3306 is SO-10, and the package type of APR340 is SOT26.
