Dual High Efficiency, Low Noise, Synchronous Step-Down Switching Regulators

The LTC1538-AUX/LTC1539 are dual, synchronous step-down switching regulator controllers which drive external N-channel power MOSFETs in a phase-lockable fixed frequency architecture. The Adaptive PowerTM output stage selectively drives two N-channel MOSFETs at frequencies up to 400kHz while reducing • Maintains Constant Frequency at Low Output Currents\n\n• Dual N-Channel MOSFET Synchronous Drive\n\n• Programmable Fixed Frequency (PLL Lockable)\n\n• Wide VIN Range: 3.5V to 36V Operation\n\n• Ultrahigh Efficiency\n\n• Very Low Dropout Operation: 99% Duty Cycle\n\n• Low Dropout, 0.5A Linear R;
