3 Description
IP6518 is a synchronized switch buck regulator and support 13 fast charge output standards, support Type-C and PD output, providing solutions for car charger, fast charge adaptor and smart power strip.
IP6518 has built-in power MOSFET, input voltage range is 10.5V to 32V, output voltage ranges from 3V to 20V, and supply up to 45W output power; support voltage and current auto adjust according to the fast charge standard. Typical output voltage and current including:
[email protected],
[email protected], 7V@3A, 9V@3A, 12V@3A,

[email protected]. Power conversion efficiency is up to 97%.
IP6518 support CV/CC output, when the output current is lower than the preset value, it is in CV mode with a constant output voltage; when the output current is higher than the preset value, it enters CC mode with a lower output voltage.
IP6518 output voltage support line compensate, the output voltage will be increased along with an increased current, providing compensation on the voltage drop introduced by the wire resistance.
IP6518 support soft start, providing resistibility on the large inrush current during circuit start up.
IP6518 support Type-C output and integrate several fast charge standards, CC1/CC2 or DP/DM support auto distinguish on the fast charge of the accessed devices, and IP6518 will adjust the output voltage and current according to the fast charge standard automatically. Supported fast charge standards including: DCP (Apple, Samsung and BC1.2), Qualcomm QC2.0/QC3.0, MTK PE+1.1/PE+2.0, Huawei FCP/SCP, Spreadtrum SFCP, USB PD.
IP6518 support multi-protection on input overvoltage and under voltage, output overcurrent, overvoltage, under voltage and short circuit.

Input voltage detect pin, should connect to VIN Ground pin Float pin, do not connect Float pin, do not connect Connect to USB DM data line Connect to USB DP data line Connect to USB Type-C CC1 line Connect to USB Type-C CC2 line Float pin, do not connect Float pin, do not connect Output voltage feedback and output current limit detect pin, a 0.1uF capacitor near this pin is recommended Output current limit detect pin, place a 0.1uF capacitor near this pin Analog ground External NMOS gate control DCDC switch node, connect to the inductor bootstrap circuit pin, place a 0.1uF capacitor close to the BST pin and LX pin, providing drive voltage for the gate of the upper MOSFET Power and heat dissipation ground
5 IC Selection Advice
IP6518 support PD 15V and 20V output, apply to smart power strip application, if PD 20V is needed, the input
voltage should be 28V and larger than 1000uF capacitor should be applied to VOUT.
IP6518C support PD 12V.
