Description
LTM4620EV
High Efficiency, Dual 13A Step-Down
Power µModule Regulator
DC1498A features the LTM
®
4620EV, the high efficiency,
high density, dual 13A, switch mode step-down power
module regulator. The input voltage is from 4.5V to 16V.
The output voltage is programmable from 0.6V to 2.5V.
DC1498A can deliver nominal 12A output current and
up to 13A maximum in each channel. As explained in
the data sheet, output current derating is necessary for
certain V
IN
, V
OUT
, and thermal conditions. The board
operates in continuous conduction mode in heavy load
conditions. For high efficiency at low load currents, the
MODE jumper (JP1) selects pulse-skipping mode for noise
sensitive applications or Burst-Mode
®
operation in less
noise sensitive applications. Two outputs can be connected
in parallel for a single 26A output solution with optional
jumper resistors. The board allows the user to program
how its output ramps up and down through the TRACK/SS
pin. The output can be set up to either coincidentally or
ratiometrically track with another supply’s output. Remote
output voltage sensing is available for improved output
voltage regulation at the load point. These features and
the availability of the LTM4620EV in a compact 15mm ×
15mm × 4.41mm LGA package make it ideal for use in
many high-density point-of-load regulation applications.
The LTM4620 data sheet must be read in conjunction
with this demo manual prior to working on or modifying
DC1498A.
