INTRODUCTION HIGH INPUT VOLTAGE WITH HIGH TRANSIENT
CAPABILITY Multioutput monolithic regulators are easy to use and п¬Ѓt
into spaces where multichip solutions cannot. Nevertheless, the popularity of multioutput regulators is tempered
by a lack of options for input voltages above 30V and
support of high output currents. The LT3692A п¬Ѓlls this
gap with a dual monolithic regulator that operates from
inputs up to 36V. It also includes a number of channel
optimization features that allow the LT3692AвЂ™s per-channel
performance to rival that of multichip solutions. The LT3692A can operate up to an input voltage of 36V
and can sustain a transient voltage up to 60V for 1 second,
making it suitable for harsh operating environments such
as those commonly found in automotive environments.
ON-DIE TEMPERATURE MONITORING
The LT3692A provides an on-die temperature monitoring
function which facilitates the application circuit design,
debugging and package thermal optimization. The voltage
at TJ pin is directly proportional to the die temperature in
Celsius (i.e., 250mV equals 25В°C and 1.5V equals 150В°C). The LT3692A is available in two packages: a 5mmВ Г—В 5mm
QFN and a 38-lead plastic TSSOP. Although Both include …
