  • The STBB3J is a fixed frequency, high efficiency, buck-boost DC-DC converter which provides output voltages from 1.2 V to 5.5 V starting from input voltage from 1.8 V to 5.5 V. The device can operate with input voltages higher than, equal to, or lower than the output voltage making the product suitable for cell lithium-Ion applications where the output voltage is within the battery voltage range. The low-RDS(on) N-channel and P-channel MOSFET switches are integrated and contribute to achieve high efficiency. The MODE pin allows the selection between auto mode and forced PWM mode, taking advantage from either lower power consumption or best dynamic performance.The device also includes soft-start control, thermal shutdown, and current limit. The STBB3J is packaged in Flip Chip 20 bumps with 2.5 x 1.75 mm.

    主要特性

    • Input voltage range from 1.8 V to 5.5 V
    • 2 A output current at 3.3 V in buck mode (VIN = 3.6 V to 5.5 V)
    • 800 mA output current at 3.3 V in boost mode (VIN 2.0 V)
    • Typical efficiency higher than 94%
    • ± 2% DC feedback voltage tolerance
    • Automatic transition between step-down and boost mode
    • Adjustable output voltage from 1.2 V to 5.5 V
    • Power save mode (PS) at light load
    • 2.0 MHz fixed switching frequency
    • Adjustable switching frequency up to 2.4 MHz (by external synchronous square signal)
    • Device quiescent current less than 50 μA
    • Load disconnect during shutdown
    • Shutdown function and soft-start
    • Shutdown current < 1 μA
    • Available in Flip Chip 20, pitch = 0.4 mm
