The LTM8045 is a μModule® (power module) DC/DC converter that can be configured as a SEPIC or inverting converter by simply grounding the appropriate output rail. In a SEPIC configuration the regulated output voltage can be above, below or equal to the input voltage. The LTM8045 includes power devices, inductors, control circuitry and passive components. All that is needed to complete the design are input and output capacitors, and small resistors to set the output voltage and switching frequency. Other components may be used to control the soft-start and undervoltage lockout.

The LTM8045 is packaged in a compact (6.25mm × 11.25mm) overmolded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8045 is available with SnPb (BGA) or RoHS compliant terminal finish.

Applications

  • Battery Powered Regulator
  • Local Negative Voltage Regulator
  • Low Noise Amplifier Power

AD-FMCXMWBR1-EBZ

FMC X-Microwave Compatible Level Translator and Power Supply Kit

FMC X-Microwave Compatible Level Translator and Power Supply Kit

Features and Benefits

  • FMC-compatible form factor
  • Powered from FMC connector with external supply possibility
  • Provides level translation and various supply values
  • Compatible with RaspberryPi X-MW controller 

Product Detail

The AD-FMCXMWBR1-EBZ is a level translator and power supply board, with FMC-compatible form factor. It is powered from the FMC connector, with the possibility to add an external supply, for application that require higher load currents. In this case, the external supply is prioritized. 

AD-FMCXMWBR1-EBZ allows multiple level translated digital communications paths between a controller/FPGA device and X-MW blocks. The module provides multiple supply voltages with high current capability, that can be used to bias the X-MW blocks or other IC’s in a prototype design.

APPLICATIONS

  • RF and Microwave designs
  • Voltage level translation
  • General-purpose software radios
  • Radar systems
  • Point to point communication systems
  • Multiple input/multiple output (MIMO) radios
  • Automated test equipment

AD-M2KPWR-EBZ

ADALM2000 Power Booster Board

ADALM2000 Power Booster Board

Features and Benefits

  • ADALM2000 compatible
  • USB Type-C powered
  • Provides two outputs with increased current sourcing capabilities

Product Detail

The AD-M2KPWR-EBZ is an ADALM2000 add-on board which increases the output current capability up to 700mA. This board can be also used as a standalone benchtop power supply with positive and negative outputs.

The AD-M2KPWR-EBZ is a USB Type C powered board capable to increase the output current of ADALM2000’s power supplies. 

Inputs:

  2. External (screw terminal connector): 4.5–18V; 20W (power supply permitting)

 

Switching between the inputs is done with a jumper.

Outputs: (2 control modes)

  1. Two variable power supplies that track M2K user supplies:
    1. 0V to 5V (400mA in USB power mode)
    2. –5V to 0V (400mA in USB power mode)
  2. Two variable power supplies, controlled from a potentiometer
    1. 1.5V to 15V (up to 700mA if powered with 18V)
    2. –15V to –1.5V (up to 700mA if powered with 18V)

 

APPLICATIONS

  • General-purpose electronic systems
  • Educational applications

LTM8045 Demo Board | Inverting/SEPIC µModule Converter, 2.8V ≤ VIN ≤ 18V, VOUT = 5V or –5V @ up to 700mA

Product Detail

Demo circuit DC1533A features the LTM8045, an inverting/SEPIC μModule converter delivering up to 700mA of output current. DC1533A is configured as an inverting converter, but can be easily changed to a SEPIC configuration for non-inverting step-up or step-down functionality. The user adjustable features of the LTM8045 such as output voltage, switching frequency, soft-start period and undervoltage lockout can be changed on DC1533A simply by modifying or installing the appropriate resistors or capacitor.
