Introduction

The MIC23030-CYMT-TR is a highly efficient, medium-voltage integrated DC-DC switching regulator with integrated high-side and low-side MOSFETs. It is designed to work with 4.75V to 40V input voltage range, while providing up to an 18V output voltage. The regulator operates with a wide input voltage range of 4.75V to 40V, and is designed to consume 1mA quiescent current under no load. It is capable of delivering an output current of up to 2A and achieves efficiencies higher than 95%. The MIC23030-CYMT-TR is ideal for applications such as voltage regulation, voltage conversion, and battery charging.

Application Field and Working Principle

The MIC23030-CYMT-TR is ideal for applications such as voltage regulation, voltage conversion, and battery charging. The product has an adjustable output voltage and fast transient response, which makes it ideal for point-of-load and system regulation applications. In addition, it can also be used in battery-powered applications, as it has an integrated load switch and Under-voltage Lockout (UVLO) protection feature. The MIC23030-CYMT-TR is a synchronous, step-down regulator that employs two external power MOSFETs and an internal voltage reference. The regulator works in a switching cycle which is based on current sensing and hysteretic control. This design minimizes the external components, thereby reducing total solution cost. When the input voltage level is higher than the output voltage level, the internal MOSFETs are switched on. The input current is then given to the output via the high-side MOSFET and low-side MOSFET, respectively. Then, the voltage signaling circuit compares the output voltage with the reference voltage and turns off the MOSFETs, thus stopping the process. The switching cycle is continuous and the MIC23030-CYMT-TR will continue to regulate the voltage until the input voltage reaches an acceptable level. The regulator has adjustable current limit, under-voltage lockout, and thermal shutdown protection features, which make it safer to use with most power supplies.
