Analog Devices, Inc. SEPIC Constant-Current/Constant-Voltage Battery Charger LT1512IS8#PBF

Description
Product Details The LT1512 is a 500kHz current mode switching regulator specially configured to create a constant-current/con stant-voltage battery charger. In addition to the usual voltage feedback node, it has a current sense feedback circuit for accurately controlling output current of a flyback or SEPIC (Single-Ended Primary Inductance Converter) topology charger. These topologies allow the current sense circuit to be ground referred and completely separated from the battery itself, simplifying battery switching and system grounding problems. In addition, these topologies allow charging even when the input voltage is lower than the battery voltage. Maximum switch current on the LT1512 is 1.5A. This allows battery charging currents up to 1A for a single lithium-ion cell. Accuracy of 1% in constant-voltage mode is perfect for lithium battery applications. Charging current can be easily programmed for all battery types. Applications Battery Charging of NiCd, NiMH, Lead-Acid or Lithium Rechargeable Cells Precision Current Limited Power Supply Constant-Voltage/Con stant-Current Supply Transducer Excitation *Maximum Input Voltage = 40V – VBAT
