Product Overview
LTM®4643 is a DC/DC step-down µModule ultrathin quad (power module) regulator with 3A per output array. Outputs can be paralleled in an array for up to 12A capability. Included in the package are the switching controllers, power FETs, inductors and support components. Operating over an input voltage range of 4V to 20V or 2.375V to 20V with an external bias supply, the LTM4643 supports an output voltage range of 0.6V to 3.3V each set by a single external resistor. Its high efficiency design delivers 3A continuous output current per channel. Only bulk input and output capacitors are needed. Fault protection features include overvoltage, overcurrent and over temperature protection. Typical applications are FPGAs, GPUs and ASICs, PCIe and backside PCB mounting.
- ±1.5% total output voltage regulation
- Current mode control, fast transient response

- Output voltage tracking
- Au pad/ball finish
- Operating temperature rating range from -40°C to 125°C
- 9mm x 15mm x 1.82mm LGA package
- Internal temperature sensing diode output
- External frequency synchronization
