Sales Briefcase
  • The L7292 is a power management device designed for consumer applications. Five bucks provide voltages for the μController and Flash memory with efficiency up to 90% in light-load condition.

    The device communicates with the μController via an I2C serial interface operating at clock speeds up to 3.4 Mbit/s.
    The regulators operate at 1.3 MHz switching frequency and enter automatically in the PFM operation to maintain high efficiency over the entire load current range.
    The device can be forced into the PWM mode by writing a bit in the serial port register.
    Low quiescent current (e.g.: All SW reg. ON with no load Iq = 175 μA).
    The L7292 device has a DSM mode to reduce the quiescent current at the minimum value (1 x SW reg. ON with no load Iq = 60 μA).
