    MIC2619 - 1.2MHz PWM Boost Converter with OVP
    Docket ↓
    1.2MHz PWM Boost Converter
    with OVP General Description Features The MIC2619 is a 1.2MHz pulse width modulated (PWM)
    step-up switching regulator that is optimized for low power,
    high output voltage applications. With a maximum output
    voltage of 35V, and a switch current of over 350mA, the
    MIC2619 can easily supply most high voltage bias
    applications, such as TV tuners.
    The MIC2619 implements a constant frequency 1.2MHz
    PWM current-mode control scheme. The high frequency
    PWM operation saves board space by reducing external
    component sizes. The additional benefit of the constant
    frequency PWM control scheme as opposed to variable
    frequency control schemes is lower output noise and
    smaller input ripple injected back to the battery source.
    The MIC2619 has programmable overvoltage protection to
    ensure output protection in case of fault condition.
    The MIC2619 is available in a low profile Thin SOT-23 6pin package. The MIC2619 has a junction temperature
    range of –40°C to +125°C.
