The MIC38C43YMM is a BiCMOS current-mode PWM controller designed for various DC-to-DC converter applications, including step-down buck regulators and flyback converters. 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. The device supports a maximum duty cycle of 96% and can start up at a voltage of 8.4V, with a minimum operating voltage of 7.6V. It is capable of operating at frequencies up to 500 kHz and includes undervoltage lockout (UVLO) with hysteresis to enhance reliability. The MIC38C43YMM is available in an 8-lead MSOP package, making it suitable for applications where space is a constraint. Its rail-to-rail output capability and fast output rise and fall times (40 ns and 30 ns, respectively) contribute to improved efficiency, particularly at lower supply voltages.
