32V (40V max) Synchronous Monolithic 1-Cell Li-Ion/Polymer Battery Charger Delivers up to 4A Charge Current
MILPITAS, CA – August 12, 2010 – Linear Technology Corporation introduces the LT3651-4.2, a highly efficient, 4A monolithic synchronous buck battery charger for 1-cell Li-Ion/Polymer batteries. The LT3651-4.2 accepts inputs up to 32V with a 40V absolute maximum rating for added system margin. Charge current is programmable and dynamically adjustable up to 4A; fully integrated synchronous power devices minimize power dissipation and save board space. User-selectable timer or C/10 termination requires no external microcontroller and simplifies the design. The LT3651-4.2 does not require external high-precision resistors to set the float voltage, further … Read More → "32V (40V max) Synchronous Monolithic 1-Cell Li-Ion/Polymer Battery Charger Delivers up to 4A Charge Current"
