Analog DevicesLTM4655IYConvertisseur CC en CC et module de régulateur de commutation

Analog Devices’ LTM4655: EN 55022B Compliant 40 V, Dual 4 A or Single 8 A Step-Down or 40 V Inverting DC-to-DC µModule Regulator

Its channels are fully independent, parallelable and capable of delivering positive or negative output polarity. Included in the package are the switching controllers, power MOSFETs, inductors, filters and support components. A 5V, 25mA LDO and clock generator enable phase interleaving of the power switching stages, for improved EMC performance.

Key Features and Benefits

●  Dual output for positive and negative voltages makes it easier to design power supply circuit for negative voltage.
●  Low EMI, EN55022 Class B Compliant reduces risks of noise issue such as frequency interference
●  Wide Vin range up to 40Vin, and wide output range up to |VOUT+ – VOUT–| ≤ 26.5V ideal for 12Vin and 24Vin bus voltage, which are common in Industrial equipment

Applications

●  Instrumentation: ATE, tester, measurement equipment
●  Industrial automation

Evaluation Board

The LTM4655 can be evaluated with the DC2594A.
