AD8280-EVALZ
Analog Devices Inc.
The AD8280 is a hardware-only safety monitor for lithium ionbattery stacks. The device has inputs to monitor six battery cellsand two temperature sensors (either NTC or PTC thermistors).The device is designed to be daisy-chained with additional AD8280devices to monitor a stack of significantly more than six cellswithout the need for numerous isolators. The output can beconfigured for an independent or shared alarm state.The AD8280 functions independently from a primarymonitor and contains a reference and LDO, both of which arepowered completely from the battery cell stack. The reference, inconjunction with external resistor dividers, establishes trip pointsfor the overvoltages and undervoltages. Each cell channel containsprogrammable deglitching circuitry to prevent alarms fromtransient input levels.The AD8280 also has two digital pins that can select variouscombinations of inputs in the case where fewer than six cells areto be monitored. Most important, it has a self-test feature, makingit suitable for high reliability applications, such as automotivehybrid electric vehicles or higher voltage industrial usage, such asuninterruptible power supplies. The AD8280 can function over atemperature range of ?40?C to +105?C. Applications Lithium ion battery backup monitor and threshold detection Electric and hybrid electric vehicle Industrial vehicle Uninterruptible power supply Wind and solar

LT8652S Demo Board | Dual Channel 8.5A, 18V, Synchronous Step-Down Silent Switcher with 16µA Quiescent Current
Analog Devices Inc.
Demonstration circuit 2523A is an 18V, 8.5A (continuous)/12A (peak) synchronous step-down Silent Switcher® with 16µA quiescent current featuring the LT8652S. The LT8652S is a compact, high efficiency, high speed synchronous monolithic step-down switching with the second generation Silent Switcher structure that minimizes EMI and reduces PCB layout sensitivity. Top and bottom power switches, compensation components and other necessary circuits are inside of the LT8652S to minimize external components and simplify design. The demo board has two outputs: 3.3V and 1.2V from a 3.6V to 18V input. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies.
The SYNC pin on the demo board is grounded by default for low ripple Burst Mode® operation. Move JP2 to FCM without SSM position can change the operation mode to forced continuous mode operation. Once JP2 is on FCM with SSM position, VCC is applied to the SYNC pin for low EMI spread spectrum operation. To synchronous to an external clock, move JP2 to SYNC and apply the external clock to the SYNC turret.
The demonstration circuit 2523A runs at 2MHz to minimize solution size. The peak efficiency is 90%. The IC temperature rise is less than 70°C when both channels run at full load, 8.5A each, at 2MHz.
The demo board has EMI filters installed for both channels. To use the EMI filter, the input should be tied to VEMI1/VEMI2, not VIN1/VIN2.
The LT8652S data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this demo manual for DC2523A.

LTM4662 Demo Board | 4.5V ≤ Vin ≤ 20V, Vout1=1.2V@15A, Vout2 = 1.5V@15A
Analog Devices Inc.
Demonstration circuit DC2527A-A features the LTM4662EY, a dual 15A or single 30A high efficiency, switch mode step-down power µModule regulator. The input voltage range is from 4.5V to 20V. With CPWR bias, input voltage can be as low as 2.375V. The output voltage range is 0.6V to 5.5V. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. The DC2527A-A offers the TRACK/SS pin allowing the user to program output tracking or soft-start period. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE_PLLIN jumper can select discontinuous conduction mode.
MODE_PLLIN pin also allows the LTM4662 to synchronize to an external clock signal (between 250kHz and 1MHz). DC2527A-A has the option of choosing both internal and external compensation circuit for LTM4662. Tying the PHASMD pin to different pins generates certain phases of CLKOUT and Channel 2. The LTM4662 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2527A-A.

LTC7820EUFD Demo Board | 2:1 Step-Down, 36V ≤ VIN ≤ 60V, VOUT = 0.5VIN @ up to 20A
Analog Devices Inc.
Demonstration circuit 2543B is a high efficiency, high
density, open loop charge pump (inductorless) DC/DC
converter. This demo board is a voltage divider which
achieves a 2:1 step-down ratio from an input voltage from
36V to 60V. The output voltage is a fixed ratio of half of the
input voltage (VIN/2) and can supply a 10A load current.
This demo board has the option to deliver a 20A maximum
load with the addition of 15 chip capacitors.
The DC2543B provides a very high efficiency solution of
98.7% when converting 48VIN to 24VOUT at 10A. When configured for a 20A output, an efficiency
of up to 98.4% is achievable for a 48VIN to 24VOUT
at 20A.
The demo board features the LTC7820, a fixed ratio high
voltage high power switched capacitor/charge pump
controller in a 4mm × 5mm QFN package. Please see
LTC7820 data sheet for more detailed information.
The DC2543B needs to be powered on with no load current
or a very small load current (less than 50mA) with
the default setup. Large load current can be applied after
VO is established. The board offers a disconnect FET
option which is controlled by the LTC7820 FAULT pin
to disconnect the load during startup as shown in the
schematic. Please refer to “Voltage Divider Prebalance
Before Switching” section in the LTC7820 data sheet for
more details regarding the startup of the voltage divider.
The board also features some protection functions
such as overcurrent and thermal shutdown to make it a
reliable solution.
