The MIC38C43YN is a BiCMOS current-mode PWM controller designed for various DC-to-DC converter applications, including step-down buck and step-up boost regulators. It operates within a 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 pin-for-pin compatible with UC3843, making it suitable for designs that require easy integration with existing systems. The MIC38C43YN is available in an 8-lead DIP package, providing flexibility for various PCB layouts. Its fast output rise and fall times of 40 ns and 30 ns, respectively, enhance performance in high-frequency applications, allowing for operation up to 500 kHz. This product is ideal for engineers looking for a reliable and efficient solution for power supply designs.
