DC3230A

Demonstration circuit 3230A features the LTM®4652, a high efficiency, bidirectional dual-phase μModule® regulator configured as a single 32A, –5V output. The input voltage range is from 4.5V to 13V. For this inverting output demo board, the maximum VIN + VOUT should not exceed 18V. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. This demo board can be configured to source or sink output load current. Hardware test setup diagrams for both conditions are described in later sections. This demo board is optimized using a default frequency of 780KHz under the 9VIN and –5VOUT condition. The current mode architecture used in LTM4652 is peak current mode control. The part operates in continuous current mode by default but can be placed in pulse-skipping mode to optimize efficiency at light loads. LTM4652 is available in a thermally enhanced 144-lead (16mm × 16mm × 4.92mm) BGA package.

• Continuous output current is a ±32A
