The MIC38HC42YM from Micrel Inc. is a high-performance, low-power BiCMOS current-mode PWM controller. It is designed for applications requiring high efficiency, such as off-line switched-mode power supplies and DC-to-DC converters.
Key electrical specifications include a 1A peak output drive current, a switching frequency up to 500kHz, and a maximum duty cycle of 96%. It features ultralow startup current (50µA typical) and low operating current (4mA typical). The device also boasts fast output rise and fall times of 20ns and 15ns, respectively.
This controller operates within a temperature range of -40°C to +85°C. It is available in a SOIC-8 package and is suitable for surface mount (SMD/SMT) applications. The standard package quantity is 95 units in a tube.
The MIC38HC42YM is pin-compatible with bipolar UC384x devices and offers improved performance due to its BiCMOS process, including rail-to-rail output swing and reduced cross-conduction currents.
