LTM4609IY Description

Short technical summary and product information.

The LTM4609IY from LT is a high efficiency switching mode buck-boost power supply module. It is designed for applications requiring an input voltage from 4.5V to 36V and an output voltage adjustable between 0.8V and 34V. This uModule regulator integrates the switching controller, power FETs, and support components, simplifying design.

 

Key electrical specifications include an output current capability of 4A DC (10A DC in Buck Mode) and efficiency up to 98%. The device features current mode control, a power good output signal, and a phase-lockable fixed frequency operation between 200kHz and 400kHz. It also offers ultrafast transient response and protection features like current foldback and output overvoltage protection.

 

The LTM4609IY is available in small surface mount footprint, low profile LGA and BGA packages measuring 15mm x 15mm. The LGA and BGA packages are RoHS compliant, while the BGA package also offers a SnPb finish option.
