五分快三计划The ACT510xQI-101 has been replaced with ACT510xQI-102

五分快三计划The ACT510x is a buck-boost converter with 4?integrated MOSFETs. It offers a high efficiency, low?component count, compact solution for a wide input voltage range from 4V to 23V applications. An advanced switch control algorithm allows the buck-boost converter to maintain output voltage regulation with input voltages that are above, below or equal to the output voltage. The system can be monitored and configured by I2C as well. The build in ADC (ACT5101) can be read for the information of input/output voltages and currents, die temperature, and generic input signals.

ACT5101EVK1-102 Evaluation Tool Users Guide

This document describes the characteristic and operation of the active semi? ACT5101EVK1-102 and?ACT5102EVK1-102 evaluation kits (EVK). It provides setup and operation instructions, schematic, layout, BOM, and test data.

五分快三计划The ACT5101EVK1-102 demonstrates the ACT5101QI-102 power management IC.

The ACT5102EVK1-102 demonstrates the ACT5102QI-102 power management IC.

The two EVKs are very similar. The difference is that the ACT5101 output voltage is set by internal registers?and it has A/D functionality. The ACT5102 output voltage is set by external resistors and it does not have A/D functionality.

Other ACT5101QIxxx and ACT5102QIxxx options can be evaluated on these EVKs by replacing the IC and any other necessary components.



The Graphical User Interface (GUI) is packaged in a ZIP file that includes the software and all necessary drivers to communicate with the ACT5101EVK1-102 Evaluation Tool, as well as all descriptions how to use the tool.

The software GUI covers all available ACT5101? and ACT5102 options.

ACT5101-101-REF01 USB PD Reference Design Users Guide

This ACT5101 + ACT4527 reference design demonstrates a 39W car charger with 27W USB-C and 12W USB-A outputs. It is USB PD 3.0 + PPS certified. It demonstrates the flexibility of the ACT5101 power management IC plus Cypress CYPD1275-24LQXQT USB PD3.0 controller to provide all USB charging protocols, including USB PD2.0, PD3.0, PD3.0 + PPS, QC2.0, QC3.0, Apple Charging, BC1.2, and more.
五分快三计划 It serves as a good starting point for any car charging or USB hub design. The power profiles and communication protocols?are easily configurable with FW modifications to the Cypress controller.

Simple FW changes have allowed certification for 27W to 45W USB-C power levels.
