The LM2647MTC from Texas Instruments is an adjustable, 200-500kHz dual-channel synchronous buck regulator controller. Designed for battery-powered applications, it features interleaved switching for reduced input capacitor and filter requirements.
Key electrical specifications include an input voltage range of 5.5V to 28V and adjustable output voltages down to 0.6V. The controller supports synchronous dual-channel interleaved switching and offers control features such as current limit, enable, frequency control, power good, and soft start. It operates in forced-PWM or pulse-skip modes and includes features like lossless bottom-side FET current sensing and adaptive duty cycle clamping.
This device is housed in a 28-TSSOP package and is designed for surface mount applications. The operating temperature range is -5°C to 125°C (TJ). Standard supervisory and control features include soft-start, power good, output under-voltage and over-voltage protection, under-voltage lockout, soft-shutdown, and enable.
Applications include notebook chipset power supplies and low output voltage, high-efficiency buck regulators.
