Analog Devices' LTM4652 Pull/Perfusion dual ±25 A or single ±50 A μModule regulators feature input overvoltage protection

ADI's LTM4652 is A step-down DC-DC μModule voltage regulator with A pull/pump dual-channel ±25 A or single-channel ±50 A output switching mode with a total DC output error of ±1.5%. The LTM4652 operates in an input voltage range of 4.5V to 18V and supports dual outputs ranging from 0.6V to 7.5V, with each output set by an external resistor. The device is designed with high energy efficiency, providing continuous current of up to ±25 A per output.

The demonstration circuit (DC3230A) uses the LTM4652 μModule regulator configured with A single 32 A, -5 V output. Input voltage range is 4.5V to 13V. For the inverse output demo board, largest VIN + | VOUT | should not exceed 18 V. The demo board can be configured to pull or instill a load current. The demo board was optimized using the default frequency of 780 kHz at 9 VIN and -5 VOUT conditions. The current mode architecture used in the LTM4652 is peak current mode control.

Features and advantage

● Pull and irrigation double channel ±25 A or single channel ±50 A current meet the requirements of automatic test application
● Wide VIN and VOUT ranges support range requirements from 12 VIN to 7.5VOUT (step-down configuration) to +12 VIN to -6 VOUT (reverse step-down configuration)
● Externally adjustable control loop compensation can optimize transient performance under various operating conditions

Applications

● Instrumentation and Measurement: ATE
● Telecommunications and network equipment
● Industrial equipment
