LTM4652: Source/Sink Dual ±25A or Single ±50A μModule® Regulator with Input Overvoltage Protection

The LTM4652 is a source/sink dual ±25A or single ±50A output switching mode step-down DC-to-DC μModule regulator with ±1.5% total DC output error. Operating from an input voltage range of 4.5V to 18V, the LTM4652 supports two outputs with an output voltage range of 0.6V to 7.5V, each set by a single external resistor. Its high-efficiency design delivers up to ±25A continuous current for each output.

Key Features and Benefits

• Source and sink dual ±25A or single ±50A current meets the requirements for automated test applications
• Wide VIN and VOUT range can support wide range requirements from 12VIN to 7.5VOUT (buck configuration), to +12VIN to -6VOUT (inverting buck-boost configuration)
• External, adjustable control loop compensation can optimize transient performance for a very wide range of operating conditions

Applications

• Instrumentation and Measurement: ATE

Evaluation Board
