DC/DC Switching Regulators: Introduction

Nisshinbo Micro Devices provides various DC/DC switching regulators that cover Buck, Boost, inverting, flyback and Buck-Boost topologies. We offer a wide operating voltage range from low operating voltage type that design for energy-harvest to 80V maximum rating products. As well as we have a wide coverage of output current, also Controller type with external MOSFET are available. Furthermore, depending on application demand, several variation can be offer such as switching modes, noise immunity, inductor built-in module and so on.

FAQ

Refer to the following FAQs for more details on functions of the DC/DC Switching Regulators and and frequently asked questions.

 What is the difference between forced PWM and normal PWM? Which type of PWM control device should I choose in what case?

 What does 'SSCG(SSFM)' stand for? What can be expected from SSCG?

 When the input voltage was raised steeply from a low value, the output of the DC/DC converter may overshoot. Why did this happen? How should I take measures against this problem?

 What is the difference between LDO's shutdown current(1) and quiescent current(2)? How much voltage does an LDO regulator output at its shutdown mode?

 What is a shutdown function for the step-up DCDC converter?
