Boost Regulator Targets Industrial And Battery-Powered Systems

    June 25, 2008
    From Texas Instruments, the TPS40210 is a 4.5-V to 52-V nonsynchronous boost controller for industrial and battery-powered applications where the output is a regulated current instead of a regulated voltage.

    From Texas Instruments, the TPS40210 is a 4.5-V to 52-V nonsynchronous boost controller for industrial and battery-powered applications where the output is a regulated current instead of a regulated voltage. The device, which uses fixed-frequency current-mode control, supports design configurations that require a grounded source n-channel FET, including boost, flyback and SEPIC topologies.

    Device type: nonsynchronous boost controller
    Input voltage range: 4.5 V to 52 V
    Output current: on-chip gate-driver sources and sinks 400 mA typ.
    Quiescent current: 2.5 mA max
    Features: programmable soft start, several overcurrent protection features including a current feedback threshold mechanism in the control loop; internal slope compensation, adjustable oscillator frequency, integrated low-side driver, external synchronization capability, 700-mV reference or a 260-mV reference in related model (TPS40211)
    Operating temperature range: -40ºC to +125ºC
    Packaging: 10-pin MSOP PowerPAD and SON packages
    RoHS compliant? yes
    Target applications: industrial and battery-powered applications as well as LED lighting
    Pricing: $1.10 each in 1,000-piece quantities
    Availability: available now

    Data sheet posted on web? yes, see http://focus.ti.com/lit/ds/symlink/tps40210.pdf
