  1. Digital set-top boxes (STBs) and satellite receivers – stepping down 12V rails to 3.3V or 5V for logic chips.
  2. IP cameras and surveillance systems – efficiently converting 12V PoE (Power over Ethernet) down to 1.8V for image sensors.
  3. Automotive aftermarket electronics – handling the noisy, 12V-14V automotive bus without failure.
  4. Industrial sensors and IoT devices – where low standby power is crucial.
  5. USB-powered devices – stepping down 5V USB to lower core voltages like 1.2V or 1.8V.

  • Configure PIR as wake source (rising edge).
  • On motion wake: timestamp with RTC, store event in flash, optionally enable Wi‑Fi and sync if network available.
  • Return to deep sleep.

  1. Input Stage: A raw DC voltage (e.g., 12V from a wall adapter or a 2-3 cell Li-ion battery pack) enters the IC via the VIN pin.
  2. Switching: The internal high-side MOSFET switches on and off at 500kHz. When on, current flows through the external inductor to the output capacitor and load. When off, the synchronous low-side MOSFET provides a path for the inductor current.
  3. Feedback (FB): The output voltage is divided down by two external resistors (R1 and R2) and fed back to the FB pin. The IC compares this voltage to an internal 0.8V reference and adjusts the duty cycle to maintain a stable output.
  4. Enable (EN): The EN pin allows for external power sequencing. Pulling it low shuts down the IC, reducing current draw to near-zero.
