Multiphase, 60V synchronous boost controller peaks at 97% : Page 2 of 2

January 11, 2017 // By Graham Prophet
LTC3897 is a multiphase synchronous boost DC/DC controller with input surge stopper and ideal-diode controller. The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor requirements, enabling the use of smaller inductors versus the single-phase equivalent.
TSSOP-38 and 5 x 7 mm QFN-38 packages. Three temperature grades are available, with operation from –40 to 125°C for the extended and industrial grades and a high temp automotive range of –40°C to 150°C. Pricing is from $5.50 (1000).
