Introduction
The LTВ®8610 and LT8611 are 42V, 2.5A synchronous
step-down regulators that meet the stringent high
input voltage and low output voltage requirements of
automotive, industrial and communications applications. To minimize external components and solution
size, the top and bottom power switches are integrated
in a synchronous regulator topology, including internal
compensation. The regulator consumes only 2.5ОјA
quiescent current from the input source even while
regulating the output.
High Efп¬Ѓciency Synchonous Operation
Replacing an external Schottky diode with an internal
synchronous power switch not only minimizes the solution size, but also increases efп¬Ѓciency and reduces power
dissipation. The efп¬Ѓciency improvement is signiп¬Ѓcant
in low output voltage applications where the voltage
drop of the Schottky diode represents a relatively large
portion of the output voltage. Figure 1 shows a 12V
to 3.3V circuit. Figure 2 shows the efп¬Ѓciency of this
circuit reaching 94%, which is 5% to 10% higher than …
