Analog Devices Inc. LTM46xx µModule Regulators

Analog Devices Inc. LTM46xx µModule Regulators are system-in-package (SiP) power management solutions with integrated DC-DC controllers, inductors, power transistors, compensation components, input and output capacitors in a compact, surface-mount BGA or LGA package. The LTM46xx µModule Regulators support functions such as Step-Down (buck), Step-Up (boost), and Step-Down and Step-Up (buck-boost), and are available with a wide range of features. Select products are low-EMI solution compliant with EN55022 class B standards, CISPR 22 (Class B) & CISPR 25 (Class 5). The compact and highly integrated design of the µModule power products addresses time and space constraints while delivering highly reliable and efficient performance.

Features

Digital Power System Management
- Control and monitor the switching regulator through a PMBus/SMBus/I²C Bus digital interface. The control and monitor functions include the following:
  - Output voltage monitoring trimming, sequencing, and margining
  - Current monitor
  - Temperature monitor
  - Fault log
- Increases system reliability
  - Tightly controlled voltage accuracy
  - Remote debugging
  - Fault reporting and logging
  - Fast reaction to faults
Buck-Boost
- Integrated magnetics and operate from a higher input voltage
High-Power, Precision-Current Sharing
- Parallel several μModule regulators to deliver high power to a load with a uniform distribution of load current
Ultra-low Noise
- Includes onboard filters and is EN55022 class B certified

Tune-a-μModule Regulator
- Gain access to internal compensation of a μModule regulator and tune loop response to obtain the highest output voltage accuracy, fast transient response, and minimum output capacitance for powering FPGAs, ASICs and microprocessors
Multiple Output
- 5, 4, 3, or 2 output μModule regulators allow current sharing of outputs to increase load current and ON/OFF or sequencing of each output
Ultrathin Packages
- Fits on the backside of the PCB or next to an FPGA or ASIC sharing the same heat sink or cold plate
