The MAX20735 is a fully integrated, highly efficient switching regulator for applications operating from 4.5V to 16V and requiring up to 40A maximum load. This single-chip regulator provides extremely compact, high-efficiency power-delivery solutions with high-precision output voltages and excellent transient response for networking, datacom, and telecom equipment.

The IC offers a broad range of programmable features through capacitors and resistors connected to dedicated programming pins. Using this feature, the operation can be optimized for a specific application, reducing the component count- and/or setting-appropriate trade-offs between the regulator's performance and system cost. Ease of programming enables using the same design for multiple applications.

The MAX20735 includes protection capabilities. Positive and negative cycle-by-cycle overcurrent protection and overtemperature protection ensure a rugged design. Input undervoltage lockout shuts down the device to prevent operation when the input voltage is out of specification. A status pin provides an output signal to show that the output voltage is within range and the system is regulating.

Applications

  • Communications Equipment
  • I/O
  • Memory VDDQ
  • Networking Equipment
  • Point-of-Load Voltage Regulators
  • Servers and Storage Equipment
  • μP Chipsets

Product Detail

The MAX20735 Evaluation Kit (EV kit) serves as a reference platform for evaluating the MAX20735 voltage regulator IC. This single-chip, integrated switching regulator provides an extremely compact, low-cost, highly efficient, fast, accurate and reliable power delivery solution for emerging low-output voltage applications up to 40A. Refer to the MAX20735 IC data sheet for more information.

The EV kit consists of a fully assembled and tested PCB implementation of the MAX20735. Jumper pins, test points, and input/output connectors are included for flexibility and ease-of-use in a wide range of applications.

The evaluation board is configured with an “edge strip” to allow high di/dt loading when evaluating the system. The +VOUT connection is on the top side, while the return (or -VOUT) is on the bottom side, directly mirroring the topside strip.

Either solder directly to the output “strip” or use the J8 terminal block to interface to a load.

Applications

  • Communications
  • Networking
  • Servers and Storage equipments
