LT3552-1 Datasheet | Linear Technology

Features - - - LTC3552-1 .. Standalone Linear Li-Ion Battery Charger and Dual Synchronous Buck Converter DESCRIPTIO The LTC®3552-1 is a plete constant-current/constantvoltage linear charger and dual fixed output DC/DC converter for single cell lithium-ion batteries. Its DFN package and low external ponent count make the LTC3552-1 ideally suited for portable applications. Furthermore, the LTC3552-1 is designed to work within USB power specifications. No external sense resistor or external blocking diode are required due to the internal MOSFET architecture. The charge voltage is fixed at 4.2V and the charge current is programmed with a resistor. The charge cycle...
