20V, 20A Synchronous
The LTC®7150S is a high efficiency monolithic synchronous
buck regulator capable of delivering 20A to the load. It uses
a phase lockable controlled on-time constant frequency,
current mode architecture. PolyPhase operation allows
multiple LTC7150S regulators to run out-of-phase, which
reduces the amount of input and output capacitors required.
The operating supply voltage range is from 3.1V to 20V.
The operating frequency is programmable from 400kHz
to 3MHz with an external resistor. The high frequency ca-
pability allows the use of physically smaller inductor and
capacitor sizes. For switching noise sensitive applications,
the LTC7150S can be externally synchronized from 400kHz
to 3MHz. The PHMODE pin allows the user control of the
phase of the outgoing clock signal. The unique constant
frequency/controlled on-time architecture is ideal for
high step-down ratio applications that operate at high
frequencies while demanding fast transient response.
The LTC7150S uses second generation Silent Switcher
technology including integrated bypass capacitors to
deliver a highly efficient solution at high frequencies with
excellent EMI performance.
