■ DESCRIPTIO The LTC®1704/LTC1704B include a high power synchronous switching regulator controller plus a linear regulator
controller. The switching regulator controller is designed
to drive a pair of N-channel MOSFETs in a voltage mode,
synchronous buck configuration to provide the main supply. The constant frequency, true PWM architecture
switches at 550kHz, minimizing external component size,
cost and optimizing load transient performance. The
LTC1704 features automatic transition to power saving
Burst Mode operation at light loads. The LTC1704B does
not shift into Burst Mode operation at light loads, eliminating low frequency output ripple at the expense of light load
efficiency. The linear regulator controller is designed to …
