The LM27241 is a single-channel high-voltage synchronous buck regulator controller from Texas Instruments. It features a 200kHz-500kHz operating frequency and is ideal for battery-powered applications such as laptops. The LM27241 uses N-channel field-effect transistors and does not require an external resistor for current limiting. It also features line feedforward and a unique adaptive duty cycle clamping technique to improve the response to input transients. The input voltage range is 5.5V-28V, and the output voltage can be adjusted down to 0.6V. The LM27241 also has soft-start, undervoltage lockout, power good signal, and enable control functions.
