1.
2MHz PWM Boost Converter with OVP
General Description
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 ...
