Product overview

Description

The STEVAL-ISA141V1 evaluation board is based on the STBB3J fixed-frequency, high-efficiency, buck-boost DC-DC converter providing 1.2 to 5.5 V output voltages starting from a 1.8 to 5.5 V input voltage. 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 MODE pin allows selecting between auto mode and forced PWM mode, taking advantage of either a lower power consumption or the best dynamic performance.
  • All features

    • 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 (external synchronous square signal)
    • Device quiescent current less than 50 µA
    • Load disconnect during shutdown
    • Shutdown and soft-start functions
    • Shutdown current <1 A
    • Available in Flip-Chip 20, pitch = 0.4 mm
    • RoHS compliant
