DESCRIPTION
The LTC®3728 is a dual high performance step-down switching regulator
controller that drives all N-channel synchronous power MOSFET stages. A
constant frequency current mode architecture allows phase-lockable frequency
of up to 550kHz. Power loss and noise due to the ESR of the input capacitors
are minimized by operating the two controller output stages out of phase.
OPTI-LOOP compensation allows the transient response to be optimized over a
wide range of output capacitance and ESR values. The precision 0.8V reference
and power good output indicator are compatible with future microprocessor
generations, and a wide 3.5V to 30V (36V maximum) input supply range
encompasses all battery chemistries.
