ВµModule Regulator Charges Supercapacitor Backup Supply,
Supporting LDO Outputs When the Input Supply Fails
Andy Radosevich The LTM8001 is a ВµModule regulator that combines a 5A switching regulator with an
array of five 1.1A low noise LDOs. The switching regulator can be set for constant
current, suitable to charge supercapacitors for power backup. The LTM8001
operates from 6V to 36V inputs. The switching regulator is capable of constant
output voltage or constant output current regulation at switching frequencies from
200kHz to 1MHz. The output of the switching regulator can be adjusted from
1.2V to 24V and the outputs of the LDOs are adjustable from 0V to 24V.
The switching regulator is set to regulate
output current at 5.6A (typical) to provide
a current limit that is above the maximum
output current of 5A. The regulated current level can be easily lowered. The inputs
for three of the LDOs are hardwired to the
output of the switching regulator, but the
input to the remaining bank of two LDOs
is undedicated, so it can be connected to
the switching regulator or elsewhere. The
bias inputs to the LDOs are undedicated
but are separated into two inputs: one
for the bank of three connected to the
switching regulator and the other for the
remaining bank of two LDOs. The outputs …

ВµModule Regulator Combines a Switcher with Five 1.1A
LDOs: Use Them for Multiple Low Noise Rails, or Parallel
Them to Spread Heat and Share Current to 5A
Andy Radosevich LDOs are often used as ripple-rejecting post-regulators on the outputs of switching
converters. LDO post-regulators can also improve regulation and transient response.
One of the top limitations on the output current capability for a post-regulator is
the LDO temperature rise, which, aside from thermal resistance, depends mainly
on its input-to-output differential voltage. The LTMВ®8001 ВµModule regulator is a
high efficiency step-down switching converter followed by an array of five low noise
LDOs with individually rated output currents of 1.1A. To spread heat and increase
available output current, the LDOs can be operated in parallel, giving designers
several easy-to-implement options for varied input-output voltage combinations.
SOME LTM8001 FEATURES
Step-Down Converter 6V to 36V VIN range Constant voltage/constant current
(CV/CC) output 5A maximum output current Adjustable 200kHz to 1MHz switching
frequency Adjustable output voltage
LDOs Adjustable output voltages Three LDOs hardwired to the switcher
output Two undedicated LDOs
SPREAD THE HEAT BY PARALLELING
THE LDOs The LTM8001вЂ™s internal LDOs are typically
set up to post-regulate the output of the
built-in switching converter. An LDOвЂ™s
temperature rise is relatively proportional …
