The MIC38HC43-1BM-TR is a fixed frequency current-mode PWM controller designed for high efficiency in DC-DC conversion applications. It features a peak output drive current of 1A and operates within a temperature range of -40¬8C to +85¬8C. The device has a low startup current of 50¬µA and a typical operating current of 4mA, making it suitable for power-sensitive applications. It supports a wide input voltage range, starting at 8.4V and operating down to 7.6V, with a maximum operating voltage of 20V. The controller is capable of current-mode operation up to 500kHz and includes undervoltage lockout (UVLO) with hysteresis. The MIC38HC43-1BM-TR is available in a 14-pin SOIC package, providing a compact solution for various power supply designs, including step-down and step-up converters.
