Description

LTM4636-1

40A DC/DC µModule Regulator with

Overvoltage/Overtemperature Protection

Demonstration circuit 2230A-B features the LT M

4636-

1EY, a 40A high efficiency, switch mode step-down power

µModule

regulator withovertemperature and input/output

overvoltage protection. The input voltage range is from

4.7V to 15V. For input voltage range from 4.7V to 5.5V,

short PVCC pin to VIN pin with R8 = R21 = 0Ω and remove

R17. The output voltage range is 0.6V to 3.3V. Derating

is necessary for certain VIN, VOUT, frequency and thermal

conditions. The board operates in continuous conduc-

tion mode in heavy load conditions. For high efficiency

at low load currents, the MODE_PLLIN jumper selects

pulse-skipping mode for noise sensitive applications or

tions. The MODE_PLLIN pin also allows the LTM4636

to synchronize to an external clock signal. DC2230A-B

has the option of choosing both internal and external

compensation circuit for LTM4636-1. Tying the PHASMD

pin to different voltage generates certain phase difference

between MODE_PLLIN and CLKOUT. The LTM4636-1 data

sheet must be read in conjunction with this demo manual

prior to working on or modifying demo circuit DC2230A-B.

Demonstration circuit 2230A-B is an easy way to evalu-

ate the performance of the LTM4636-1EY. Please refer to

Figure1 for proper measurement equipment setup and

follow the procedure below.

1. Place jumpers in the following positions for a typical

application:

MODE RUN

CCM ON

2. With power off, connect the input power supply, load

and meters as shown in Figure 1. Preset the load to 0A

and VIN supply to 12V.

3. Turn on the power supply at the input. The output volt-

age should be 1.0V ± 1.3% (0.987V to 1.013V).

4. Vary the input voltage from 6V to 15V and adjust the

load current from 0A – 40A. Observe the output volt-

age regulation, ripple voltage, efficiency, and other

parameters.

5. (Optional) For optional load transient test, apply an

adjustable pulse signal between IOSTEP_CLK and GND

test points. The pulse amplitude sets the load step cur-

rent amplitude. Keep the pulse width short (<1ms) and

pulse duty cycle low (<5%) to limit the thermal stress

on the load transient circuit.

6. (Optional) LTM4636 can be synchronized to an external

clock signal. Place the JP1 jumper on EXT_CLK and

apply a clock signal (0V to 5V, square wave) on the

MODE_PLLIN test point.
