DEMO MANUAL DC1041A-B

DESCRIPTION

LTM4601HV

5VIN to 28VIN,

12A Step-Down

µModule Regulator

Demonstration circuit DC1041A-B features the

LT M

4601HVEV, a 12A high efficiency, high density

switch mode step-down converter. The input voltage

range is from 4.5V to 28V. The output voltage is jumper

selectable for popular voltages from 0.6V to 5V. The PLLIN

pin supports synchronizing the μModule

regulator to

an external clock. The TRACK/SS pin allows the user to

program output ramp-up and ramp-down rates which

may coincidentally or ratiometrically track with another L, LT, LTC, LTM, μModule, Linear Technology and the Linear logo are registered trademarks of

±5% from the nominal value is available via the margin

control pins MARG0 and MARG1. The LTM4601HV data

sheet must be read in conjunction with this demo manual

prior to working on or modifying demo circuit DC1041A-B.

QUICK START PROCEDURE

Figure 1. Demo Board Setup

Demonstration circuit DC1041A-B is an easy way to evalu-

ate the performance of the LTM4601. Please refer to

Figure1 for proper measurement equipment setup and

follow the procedure below:

1. With the power supply off, connect the input power

supply, load and meters as shown in Figure 1. Preset

the load to 0A and power supply voltage within the

LTM4601’s operating input voltage range.

2. Place jumpers in the following positions for a typical

1.5VOUT application:

MARG0 MARG1 RUN VOUT SELECT

LO LO ON 1.5V

3. Turn on the power at the input. The output voltage

should be 1.5V ±1%.

4. Once the proper output voltage is established, adjust the

load within the operating range and observe the output

voltage regulation, ripple voltage, efficiency and other

parameters. Output ripple should be measured at J4

with a BNC cable.

5. For optional load transient test, apply an adjustable

pulse signal between IOSTEP (E3) and GND pins.

Pulse amplitude sets the current step. The pulse signal

should have very small duty cycle (<15%) to limit the

thermal stress on the transient load circuit. The output

transient current can be monitored at BNC connector

J3 (10mV/A).

6. For Margining function test, place jumper MARG0 and

MARG1 in the configurations shown in the following

table, measure the output voltage at J4.
