HL7603

The HL7603 provides a power supply solution for products powered by Li-Ion Battery, Silicon Anode Battery or LiFePO4 Battery. By combining built-in power transistors, synchronous rectifier, and low supply current, this IC is optimized for single-cell portable applications like in mobile devices, tablet PCs, wearable devices or accessories. The HL7603 is a boost regulator designed to provide a minimum output voltage from a single-cell Li-Ion battery, even when the battery voltage is below system minimum requirement. This extends the battery run-time and overcomes input current and voltage limitations of the powered system. The HL7603 supports a maximum load current of 4A in continuous mode and 5A in peak mode (<10ms). The regulator can transit smoothly between Bypass Mode and normal Boost Mode and also can work under Forced Bypass Mode for minimizing quiescent current. The HL7603 is available in a 16-bump, 0.4mm pitch, Wafer-Level Chip-Scale Package (WLCSP).
