The MIC38C43BMM is a high-performance, current-mode PWM controller designed for various DC-to-DC converter applications, including step-down buck regulators and step-up boost regulators. It operates within an ambient temperature range of -40¬8C to +85¬8C and features a low start-up current of 50 OºA and a quiescent operating current of 4 mA, making it suitable for low-power applications. This controller supports a maximum supply voltage of 20V and is capable of operating at frequencies up to 500 kHz. It includes undervoltage lockout (UVLO) with hysteresis, rail-to-rail CMOS outputs, and a trimmed 5V bandgap reference. The device is pin-for-pin compatible with UC3842/3843/3844/3845, allowing for easy integration into existing designs. The MIC38C43BMM is available in an 8-lead MSOP package, which is advantageous for space-constrained applications.
