The LTC1929 and LTC1929-PG, current mode DC/DC controllers that drive two synchronous buck stages out of phase, are described.
PolyPhase DC/DC converter
The LTC1929/LTC1929-PG are current mode DC/DC controllers that drive two synchronous buck stages out of phase. The 2-phase architecture reduces the number of input and output capacitors without increasing the switching frequency. The relatively low switching frequency and integrated high current MOSFET drivers help obtain high power conversion efficiency for low voltage, high current applications. Because of output ripple current cancellation, lower value ...
