The boost converter is based on a hysteretic controller topology using synchronous rectification to obtain maximum efficiency at minimal quiescent currents. The output voltage of this device is set internally to a fixed output voltage of 3.3 V. The converter can be switched off by a featured enable pin.

Description . This design implements a bi-directional, non-isolated buck boost power converter, ideal for solar microconverters, hybrid electric vehicles (HEV) including Regeneration (Regen or Recuperation), and battery charging applications. "the forward converter small-signal gains": a short PowerPoint which shows how my new models match calculations in both VM and CM for a forward converter. New models to download. PWM Switch LTspice: Mark Dimattina offers a way to implement the PWM CM version in LTspice. Thank you for sharing your models Mark. As it is, the V1 on time is too long; watch inductor current in the first cycle. The converter is also operating in discontinuous mode despite a significant load, so the output voltage swing is huge. I'd say start design calculations as if this were a 36v buck converter, and then work in how much of the on-time can be shared by the 12v source. The Calculator Tyler Cooper For this simple calculator, enter in the freqency, voltage ranges and current ranges and the duty cycle, inductor and current requirements will be displayed! Also, for a Boost Converter the V(a_c) signal will be negative so limiting the signal to a minimum value will not work for a Boost converter. To keep a common model for Buck and Boost converters an a_c_lim signal with a dead zone of +/-1 mV was introduced. Figure 3 V(a_c_lim) with Dead zone The boost converter is a high efficiency step-up DC/DC switching converter. The converter uses a transistor switch, typically a MOSFET, to pulse width modulate the voltage into an inductor. Rectangular pulses of voltage into an inductor result in a triangular current waveform.
