The MIC38C44-1BM is a BiCMOS Current-Mode Pulse Width Modulation (PWM) controller manufactured by Micrel Inc. This device is designed for high-performance applications and offers several improvements over traditional bipolar 384x devices. It operates at a fixed frequency and features current-mode control for enhanced regulation.
A key feature of the MIC38C44-1BM is its undervoltage lockout circuitry. This allows the controller to start up reliably at 14.5V and continue to operate down to a minimum voltage of 9V, ensuring stable performance across a range of supply conditions.
As a PWM controller, the MIC38C44-1BM is suitable for various power supply designs where precise control of switching is required. Its BiCMOS technology provides a balance of speed and low power consumption. The device is pin-compatible with older bipolar controllers, facilitating upgrades in existing designs.
