ZSPM1005

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

The ZSPM1005 is a configurable true-digital single-phase PWM controller for high-current, non-isolated DC/DC supplies. It operates as a synchronous step-down converter in a single-rail and single-phase configuration. The ZSPM1005 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. To facilitate user configuration of the part, a set of configuration options can be pre-programmed in the ZSPM1005 that can be selected by setting the values of two external resistors. IDT's Pink Power Designer™, a PC-based, user-friendly interface to the ZSPM1005, can be used to expedite the design of the digital compensator. It offers intuitive configuration methods for additional features, such as protection and sequencing. Once the part is programmed, resistor options can be used to select the required configuration without a digital bus.

Features

  • Programmable digital control loop
  • Advanced, digital control techniques: Tru-sample Technology™, State-Law Control™ (SLC), and Sub-cycle Response™ (SCR)
  • Improved transient response and noise immunity
  • Protection features: over-current protection, over-voltage protection (VIN, VOUT), under-voltage protection (VIN, VOUT), overloaded startup, and restart and delay
  • Support for SMOD and ZCD drivers
  • Fuse-based one-time programmable (OTP) nonvolatile memory for improved reliability
  • Operation from a single 5V or 3.3V supply
  • 2-pin configuration for compensation, output voltage, and more
