PM2300 - 3AMP CHARGER FOR TABLETS AND SMARTPHONES
Highly efficient and BOM optimized high current charger for single-cell or parallel Li-Ion batteries.png)
Most current tablets use high capacity single-cell Li-Ion batteries or two batteries in parallel, which require several hours to recharge. The PM2300, with its high charging current capability, charges batteries in half the time of conventional charging circuitry.
The PM2300 has a dual DC/DC structure that allows the integration of a high performance power MOS. This leads to improved efficiency at lower cost.The PM2300 also brings an optimized PCB footprint through the use of smaller and cheaper coils than those found in existing solutions.
KEY BENEFITS
- Charges the battery at 3A instead of 1.5A max
- Halves the battery charging time: less than 3h for a 25Ah battery
- Charge even during intensive use cases: typical intensive use cases consume around 1A
- Up to 60% PCB footprint reduction compared to existing solutions
KEY FEATURES
- 3A DC/DC step-down battery charger
- High efficiency: up to 92% with 1µH coil
- Dual path integrated power FET
- I²C control
- LED driver for charging indicator
- Interrupt and wakeup signal
- Wall charger power optimization
TARGETED APPLICATIONS
- Tablet
- Smartphone
- Mobile phone
- Portable applications
