OPERATION
The LTM8027 is a standalone nonisolated step-down
switching DC/DC power supply with an input voltage
range of 4.5V to 60V that can deliver up to 4A of output
current. This module provides a precisely regulated output
voltage up to 24V, programmable via one external resistor.
Given that the LTM8027 is a step-down converter, make
sure that the input voltage is high enough to support the
desired output voltage and load current. A simplified block
diagram is given above. The LTM8027 contains a current
mode controller, power switching element, power induc-
tor, power MOSFETs and a modest amount of input and
output capacitance.
The LTM8027 is a fixed frequency PWM regulator. The
switching frequency is set by simply connecting the ap-
propriate resistor from the RT pin to GND.
A linear regulator provides internal power (shown as
INTV CC on the Block Diagram) to the control circuitry.
The bias regulator normally draws power from the V IN
pin, but if the BIAS1 pin is connected to an external volt-
age higher than 8.5V, bias power will be drawn from the
external source (typically the regulated output voltage).
This improves efficiency. The RUN pin is used to enable
or place the LTM8027 in shutdown, disconnecting the
output and reducing the input current to less than 9μA.
