LMZM33604: Inverting Buck Power Supply IC

Part Number: LMZM33604
Other Parts Discussed in Thread: LM25116, LM5116, LM5088, LM25088,

Tool/software:

Hi TI Team,

We want to design design power supply DC DC converter for input voltage 12V output voltage -13.5V with 1A output current capability.

  • For generating 12V to -13.5V DC, the TI Power Designer suggested using inverting buck-boost converters such as LM25116, LM5116, LM5088, and LM25088. However, the datasheets for these parts do not explicitly mention support for negative or inverting voltage outputs. While the LMZM33604 supports inverting applications, its 16x10mm size does not fit our requirements.
  • Could you please confirm if there are any other smaller-sized inverting DC-DC buck regulators that can generate -13.5V from 12V?
