Product overview

Description

The STPMIC06 is a power management device with four high efficiency buck regulators.

Buck regulators can operate in parallel with a single output inductor to support up to 6A load or use external low side for higher load.

The regulators operate from 500 kHz up to 1.5 MHz switching frequency and enter automatically in PFM operation to maintain high efficiency over the entire load current range.

  • All features

    • Wide input voltage range from 4.5V to 15.6V
    • 4 independent and fully programmable buck regulators
    • Integrated NMOS supporting 3A maximum load
    • Output voltage range from 0.5V to 3.3V (extended range from 3.0V to 5.4V with external resistor divider)
    • PMBus® serial interface supports 1Mbit/s protocol (high-speed mode)
    • Embedded NVM to store customized default parameters configuration such as
      • Output voltage, power up sequence, delay and startup slope
      • Enable and PGOOD configuration
      • Programmable current limit
      • Phase interleaving in steady state condition
      • Current limit
    • Dynamic voltage scaling (DVS) support with programmable slope
    • Automatic PFM / PWM modes for efficiency optimization
    • Low quiescent current stand-by mode
    • Auto discharge function on reset
    • OTP, UVLO, OVP, UVP, OCP and short circuit protection
