  • The L6739 is a single-phase step-down controller with integrated high current drivers that provides complete control logic and protection to realize a DC-DC converter.

    The device flexibility allows to manage conversions with power input VINas low as 1.5 V and the device supply voltage ranging from 5 V to 12 V bus.
    The L6739 device features a proprietary algorithm that allows light-load efficiency optimization, boosting efficiency without compromising the output voltage ripple.
    The integrated 0.8 V reference allows generation of output voltages with ± 0.5% accuracy over line and temperature variations.
    The oscillator is programmable up to 600 kHz.
    The L6739 provides a programmable overcurrent protection and overvoltage protection. The current information is monitored across the inductor DCR.
    The L6739 device is available in a VFQFPN 16 - 3 x 3 mm package.
