Dual-Channel Isolators with

Integrated DC/DC Converter, 50 mW

ADuM5240/ADuM5241/ADuM5242

GENERAL DESCRIPTION

Preliminary Technical Data

FEATURES

Integrated isolated DC/DC converter

Regulated 5V/10 mA output

The ADuM524x¹are dual-channel digital isolators having an

integrated DC/DC converter. Based on Analog Devices’

iCoupler® technology, the DC/DC converter provides up to

50 mW of regulated, isolated power at +5V. This eliminates the

need for a separate isolated DC/DC converter in low-power

isolated designs. Analog Devices’ chip-scale transformer

iCoupler^®technology is used both for the isolation of the logic

signals as well as for the DC/DC converter. The result is a small

form-factor total-isolation solution.

Dual dc-to-10 Mbps (NRZ) signal isolation channels

Narrow body SOIC 8-lead package

High temperature operation: 105°C

Precise timing characteristics:

3 ns maximum pulse-width distortion

3 ns maximum channel-to-channel matching

70 ns maximum propagation delay

High common-mode transient immunity: > 25 kV/μs

Safety and regulatory approvals (pending)

UL recognition

ADuM524x units may be used in combination or with other

iCoupler products to achieve greater channel counts.

ESD CAUTION

APPLICATION INFORMATION

When these guidelines are followed, pre-production samples

may be used for prototype and evaluation. As mentioned above

this issue will be corrected in final silicon and the ADuM524x

will operate at specified load and temperature conditions.

DC/DC CONVERTER

The ADuM524x can be operated with the internal DC/DC

enabled or disabled. With the internal DC/DC converter

enabled, the Pin 8 isolated supply provides output power as well

as power to the part’s isolated-side circuitry. Since the power

consumed by the ADuM524x is a function of the input signals’

data rate, the available isolated output power is determined by

the data rate at which the part’s data channels are operating.

The ADuM524x’s internal DC/DC converter state is controlled

by the input V_DDvoltage as defined in Table 6. In normal

operating mode, V_DDis set between 4.5 V and 5.5 V and the

internal DC/DC converter is enabled. When/if it is desired to

disable the DC/DC converter, V_DDis lowered to a value between

2.7 V and 4.0 V. In this mode, the V_ISOsupply is supplied by the

user and the ADuM524x’s signal channels continue to operate

normally.

¹Value of load capacitor C3 in Figure 8

PC BOARD LAYOUT

The ADuM524x digital isolators require no external interface

circuitry for the logic interfaces. Power supply bypassing is

strongly recommended at the input and output supply pins as

shown in Figure 8. For the ADuM5240 and ADuM5241, a

bypass capacitance (C₁) of 44 μF is required at the V_DDinput to

ensure proper power-up. For all models bypass capacitance is

recommended with C₂=0.1 μF on the non-isolated side and

C₃=10 nF on the isolated side. Due to high inductance

associated with larger capacitors such as C₁, it is recommended

that both C₁and C₂be used on the ADuM5240 and

GUIDELINES FOR PRE-PRODUCTION SAMPLES

Pre production samples meet all data sheet specifications;

however, a limitation in the internal circuitry of the ADuM524x

prevents proper start-up under all load conditions. This

limitation will be corrected in the final product.

At certain temperature and load conditions the ADuM524x will

not regulate its V_ISOoutput to the 5.25V target voltage at

converter start-up. The output stabilizes at just under 4V with

no external load or as low as 3V with an external load. If the

converter starts successfully, the output voltage will continue to

regulate properly even as temperature and load conditions

change.

ADuM5241. The bypass capacitors should be placed as close as

possible to the ADuM524x device.

In cases where EMI is a concern, inductance should be added

between the system supply and ground and the ADuM524x

supply and ground as shown in Figure 8. Inductance can be

added in the form of discrete inductors or ferrite beads, and it’s

recommended the value correspond to an impedance between

50Ω and 100Ω at approximately 300MHz.

The start-up issue is affected by several circuit and

environmental conditions: slew rate applied to V_DD1, ambient

temperature, and V_ISOcapacitive load. The recommendations in

the PC board layout section address the V_DD1slew rate

dependence in most cases. Good results have been obtained

when the system power supply slews at ~0.5V/μS. Faster slew

rates can be tolerated but should be verified over temperature.

Table 14 contains guidelines for the maximum reliable start-up

temperature for two common values of load capacitance.

The V_ISOstart-up issue is strongly temperature dependant. The

ADuM542x dissipates between 40 and 63mW under normal

operation, causing the internal temperature of the device to be

higher than ambient during normal operation. A “warm start”

after the device has reached its equilibrium temperature is the

worst case condition and will give the highest probability of

incorrect regulation of output voltage. The guidelines in Table

14 are based on “warm start” at full load. Cold start will be

successful at higher ambient temperatures.

Figure 8. Recommended Application Circuit. C₁may be

omitted for ADuM5242, and L₁and L₂should be included

where EMI is a concern.
