Announcement: Check out our latest video on the HL5301, the industry's smallest SIM card level translator.


The HL7130 is the low voltage fast charger for 1 cell Li-ion and Li-polymer batteries. The device integrates a dual phase switched capacitive converter and reverse blocking MOSFET (QRB FET) and shows 96.5% efficiency for 4V output and 6A charging current from 8V input.

The switched capacitive converter architecture of this device and the integrated FET are optimized to enable a 50% duty cycle operation under CP Mode, CP Mode allows the output voltage VOUT is around half of the input voltage VIN and the input current to be half of the current delivered to the output, reducing the power loss over the input power cable as well as limiting the temperature rise in the application. The dual-phase architecture reduces the input capacitance requirements as well as input voltage ripple.

Besides CP Mode, the device has BP Mode. BP Mode allows VIN forwardly passing through the internal power FETs to VOUT directly.
