The USB Energy Supply (USB PD) 45W Cell Charger reference design might help design energy provides with low standby energy, full-regulation output voltage, excessive effectivity, and reliability.
Rechargeable digital units like smartphones, tablets, and notebooks have restricted battery capacities; therefore environment friendly and quick charging is crucial for uninterrupted utilization. The charging strategies guarantee handy energy replenishment on the go, enabling customers to remain linked and productive. The superior charging strategies assist optimize charging pace, reduce warmth technology, and guarantee system security. NXP has launched a Common Serial Bus Energy Supply (USB PD) 45W Cell Charger reference design to simplify the USB charger design course of. With the USB PD 45W Cell Charger, energy provides that includes low standby energy, full-regulation output voltage, excessive effectivity, and reliability could be designed. The design particularly caters to energy provides for cellular and pocket book units, accommodating energy necessities of as much as 100W. The reference design streamlines the design course of for customers by minimizing the necessity for exterior parts.
The design relies on the quasi-resonant controller, synchronous rectifier controller, in addition to USB-PD Kind-C and Fast Cost (QC) 4.0 controller. The USB PD 45W Cell Charger is designed to supply a most output energy of 45 W, with a most present of three A. It gives the flexibleness to pick output voltages starting from 5 V as much as 20 V. The design supplies an environment friendly and efficient answer for USB Energy Supply and fast cost functions, guaranteeing low present ripple and excessive effectivity. The design supplies multi-protocol assist for USB Energy Supply (USB-PD) 2.0 and three.0 and Fast Cost 4.0. The options like no-load energy, low audible noise, and low output voltage ripple make sure the excessive efficiency of the USB PD charger.
The compact design excels in thermal administration, guaranteeing secure operation with a complete set of hardware-integrated safety options. The reference design minimizes growth time and reduces analysis and growth prices. The USB PD charger operates at an AC principal voltage of 90 V(AC) to 264 V(AC) and delivers a most output energy of 45 watts. The ambient temperature of the adapter contained in the casing ranges from -40 °C to 85 °C. Working inside an enter frequency vary of 47Hz to 63Hz, the design demonstrates distinctive effectivity, surpassing 92%.
This reference design has been examined by NXP. It comes with a Invoice of Materials (BOM), schematics, Printed circuit board (PCB) format, and so forth.
