PN8162 + PN8307H super thin small volume PD 20W fast charge solution

With the formal sale of iPhone12, the earphones and chargers are no longer standard, and there is no standard charger. For charger vendors, this is also a business opportunity. After the iPhone 12, the demand for major platform chargers has skyrocketed, domestic The charger manufacturer has no supply, Based on PN8162 + PN8307h super thin small volume PD 20W fast charge program! PN8162 integrates a current mode controller and power MOSFET dedicated to high performance and peripheral components, which provides an extremely comprehensive and excellent protection function, including output overvoltage. Protection, progressive overcurrent protection, overload protection, soft start, input undervoltage protection. The best efficiency of ultra-low standby power consumption and full-voltage range is achieved by QR-PWM, QR-PFM, Burst-Mode, and the low power consumption structure technology of special devices. Frequency modulation technology and Soft Driver technology fully guarantees good EMI performance. Pd 20W fast charge program highlights ★ The original main control PN8162 and the secondary synchronization PN8307H achieve power integration, benefited from patented smart MOS technology, saving starting resistance, CS detection resistor, etc., PCBA size: 28mm * 28mm * 24mm; ★ PN8162 uses PDFN special power packages, compared to traditional SOP8, encapsulated thermal resistance from 80 ° C / W to 15 ° C / W, significantly increase the charger power density; single DRAIN foot, high and low pressure pin climbing distance greater than 1.2 MM, safe and reliable; ★ PN8162 uses load adaptive valley opening technology, thoroughly solving the conduction problem caused by small volume charger switch interference source to LN line shift current, EMC margin is greater than 6dB; ★ PN8162 works to force DCM mode, so that the SR spike voltage can be controlled within 51V, 60V pressure-resistant PN8307 can ensure that the voltage DE-Rating is sufficient, and the overall solution cost is reduced. ★ PN8162 built-in input undervoltage protection, monitoring the city's electricity through DMG, preventing the power supply abnormality; ★ PN8162 9-38V VDD power supply, PN8307 3-24V VCC power supply, no external LDO is required within the 3-12V output voltage; ★ PN8162 built-in line voltage compensation, according to the city's automatic adjustment internal peak current reference, the full voltage range OCP accuracy is within 10%; ★ HUSB339B protocol supports PD3.0, PD2.0, QC3.0 / QC2.0, AFC, FCP, BC1.2 DCP, and 5V2.4A. The 20W PD fast charge program uses high integrated chip PN8162 + PN8307H, supports 12V1.67A; 9V2.22A; 5V3A output, built-in MOS power chip and fast charge chip, the solution is very small, minimize chip peripheral device The quantity reduces the footprint of the PCB board.
