ADI’s Isolated Error Amplifiers
Outperform Optocouplers and
Shunt Regulators in Power Supply
Applications
ADI have introduced isolated error
amplifiers that provide power supply
designers with a higher performing,
single-chip alternative to isolation
techniques based on optocouplers
and shunt regulators. Designed for
linear feedback power supplies using
primary side controllers, the
ADuM3190 and ADuM4190 isolated
error amplifiers have a 400-kHz
bandwidth, with 0.5% typical initial
accuracy at 25°C and 1% total
accuracy over the extended
temperature range of -40˚C to
+125˚C. This provides manufacturers
of ac-to-dc and dc-to-dc power
supplies, including those that are
DOSA (Distributed-power Open
Standards Alliance)-compliant, with a
significant upgrade in speed and
operating temperature range, as well
as a 5x improvement in transient
response.
Features
Bandwidth: 400 kHz
0.5% initial accuracy at 25°C
1% total accuracy over -40˚C to
+125˚C
Low power operation: <7 mA
Isolation voltage:
- ADuM3190: 2.5 kVrms
- ADuM4190: 5 kVrms (reinforced)

Murata-PS' Extends Power
Rating of 5.2 kV Isolation Miniature
DC/DC Converters
The New safety approved MEJ2 is a
fully encapsulated compact through-
hole 2 Watt DC/DC converter. The
series provides a pin-compatible
upgrade path from Murata's NMJ,
MEV1 and NMV series.
In a compact SIP format, the MEJ2
series has about twice the power
density of its predecessor, the NMJ
series, while offering safety agency
recognition according to UL60950 for
basic/supplementary insulation for
voltages up to 200 Vrms.
The series maintains high levels of
efficiency of 79% typical at light loads,
saving power, reducing temperature
rise and increasing product reliability.

Diodes' AL8807A : Wide Analog
Control Voltage Extends LED Lamp
Dimming Range
1. Over-temperature condition
2. Open-LEDs
3. Short-LEDs
The AL8807A is an enhancement of
Diodes' low EMI buck high brightness
LED driver AL8807. It extends the
analog dimming range in excess of
10:1.
The AL8807A provides protection
against a number of potential faults
within a lamp:
Switches itself off
Automatically stops switching
Continues switching but at
reduced duty cycle minimizing
power dissipation
The AL8807A can operate at up to
1MHz - reducing the size of external
components. The small MSOP-8EP
package size (same footprint as
AL8806/7) coupled with the need for
only 4 external components produces
a small solution footprint.
The accuracy, temperature range, cost
and analog dimming range make it
ideally suited to dimmable LED
lighting applications.
