LTM4655IY#PBF

LTM®4655 is an ultralow noise 40V, DC/DC μModule® regulator designed to meet the radiated emissions requirements of EN55022. Its channels are fully independent, parallelable and capable of delivering positive or negative output polarity. Conducted emission requirements can be met by adding standard filter components. 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. Typical applications are automated test and measurement, avionics and industrial control systems, video, imaging and instrumentation.

• Two fully independent channels, each configurable for positive or negative output voltage polarity
• ±1.67% total DC output voltage error over line, load and temperature
• Constant-frequency current mode control, overcurrent and overtemperature protection
• Power good indicators and programmable soft-start
• Input DC voltage in positive-VOUT configuration range from 3.1 to 40V (VOUTn–=GND, TA=25°C)
• Input supply bias current is 30μA max (shutdown, RUNn=GND)
• Input supply current is 2.9A typical (CLKINn open circuit, IOUTn+=4A)
• Input supply current in shutdown is 4µA typical (shutdown, RUNn=GND)
• 144-lead BGA package
• Temperature rating range from -40°C to 125°C
