Implementing A Sewing Machine Controller With An Mc9rs08ka2 Microcontroller


Posted on Feb 6, 2014

The MIC2199 is a synchronous buck switching Regulator controller. An all N-Channel synchronous architecture and powerful output drivers allow up to a 20A output current ca- pability. The MIC2199 operates from a 4. 5V to a 32V input and CAN be programmed for output voltage from 0. 8V to 6V. The 300kHz switching frequency allows the use of smaller ind

uctor and the external COMP pin allows different output capacitor to be used for optimum transient response. To keep the pin count to a bare minimum, the MIC2199 does not offer an external soft-start pin that allow to reduce inrush current by delaying and slowing the output voltage rise time by connecting a capacitor on this pin. Figure 1 shows the output voltage waveform for a stan- dard MIC2199 circuit that takes about 120 µs and exhibits an output voltage overshoot for VIN = 12V, VOUT = 3. 3V, I LOAD = 0A. Figure 2 shows a simple and inexpensive way of implementing external soft-start on the MIC2199 by using a capacitor, C1 and a Diode 1N4148 between VOUT and FB pins.
