ZSPM1363BA1R1

ZSPM1363 ZSPM1363 True Digital PWM Controller (Dual-Phase, Single-Rail) Brief Description Features The ZSPM1363 is a configurable true-digital dualphase PWM controller for high-current, non-isolated DC/DC supplies. It operates as a synchronous stepdown converter in a single-rail and dual-phase configuration. • The ZSPM1363 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 2 an I C interface facilitate configuration. • The PC-based IDT 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. • • • • • • • Benefits • • • • • Fast configurability and design flexibility Simplified design and integration Reduced component count through system level integration Simplified monitoring for system power and thermal management Higher energy efficiency across all output loading conditions • • • • • • • • Physical Characteristics • • • • Operation temperature: -40°C to +125°C Operation from a single 5V or 3.3V supply VOUT max: 5V Lead-free (RoHS compliant) 32-pin QFN package (5mm x 5mm) Datasheet Programmable digital control loop Dual-phase, single-rail solution Power modes (phase addition/drop) Optional PMBus™ address selection without external resistors VIN feed-forward Advanced, digital control techniques  Tru-sample Technology™  State-Law Control™ (SLC)  Sub-cycle Response™ (SCR) Improved transient response and noise immunity Discontinuous conduction mode (DCM) and phase dropping at light loads Protection features  Over-current protection  Over-voltage protection (VIN, VOUT)  Under-voltage protection (VIN, VOUT)  Overloaded startup  Restart and delay 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 ZSPM1363 Typical Application Diagram ZSPM1363 QFN32 5mm x 5mm ZSPM9060 PQFN 6mm x 6mm Current Sensing MOSFET Driver Available Support • • VOUT Digital Control Loop Evaluation Kit PC-based Pink Power Designer™ GUI Power Management Housekeeping and Communication © 2016 Integrated Device Technology, Inc.
