True Digital PWM Controller (Single-Phase, Single-Rail)

Overview

TopologyOther Topology

Description

The ZSPM1063 is a configurable true-digital single-phase PWM controller for high-current, non-isolated DC/DC supplies. It operates as a synchronous stepdown converter in a single-rail and single-phase configuration. The ZSPM1063 integrates a digital control loop, optimized for maximum flexibility and stability, as well as load step and steady-state performance. In addition, a rich set of protection and monitoring functions is provided. On-chip, non-volatile memory (NVM) and an I2C interface facilitate configuration. The PC-based ZMDI Pink Power Designer™ graphical user interface (GUI) provides a user-friendly and easy-to-use interface to the device for communication and configuration. It can guide the user through the design of the digital compensator and offers intuitive configuration methods for additional features, including protection and sequencing.

Features

  • Programmable digital control loop
  • Single-phase, single-rail solution
  • Optional PMBus™ address selection without external resistors
  • VIN feed-forward

  • Protection features
  • Fuse-based NVM for improved reliability
  • Re-programmable one-time programmable (OTP) memory feature
  • VOUT sequencing from external source
  • Pin-strapping options: RTUNE and RVSET
  • Current balancing between both phases
  • Tri-state PWM outputs
  • Additional driver support options
  • Constant on-time controller (COT) in DCM

Typical applications

  • Industrial Applications
  • Telecom Switches/ Servers and Storage/ Base Stations/ Network Routers/
  • Single-Rail/Single-Phase Supplies for Processors,ASICs, FPGAs, DSPs
