The MIC38HC44-1YN is a fixed-frequency, current-mode Pulse Width Modulation (PWM) controller manufactured by Microchip Technology. This BiCMOS device offers high performance and low power consumption, making it suitable for various power supply applications.
Key electrical specifications include a switching frequency of 500kHz, a maximum duty cycle of 50%, and a wide operating voltage range of 9V to 20V. The controller features a startup voltage of 14.5V and provides an output isolation capability. It is designed with internal switches and supports frequency control.
The MIC38HC44-1YN is housed in a 14-DIP package, designed for through-hole mounting. It operates within a temperature range of -40°C to 150°C (TJ). The device also boasts fast output rise and fall times, low startup current (50µA typical), and low operating current (4mA typical).
This PWM controller is ideal for applications such as current-mode, off-line, switched-mode power supplies, DC-to-DC converters, buck regulators, boost regulators, flyback, and forward converters.
