The LM2657 requires only N-channel FETs for both the upper and lower positions of each stage. It features line feedforward to improve the response to input transients. At very light loads, the user can choose between the high-efficiency Pulse-skip mode or the constant frequency Forced-PWM mode. Lossless current limiting without external sense resistors is made possible by sensing the voltage drop across the bottom FET. A unique adaptive duty cycle clamping technique significantly reduces peak currents under abnormal load conditions. The two independently programmable outputs switch 180° out of phase (interleaved switching), reducing input capacitor and filter requirements. Input voltage range is 4.5V to 28V while output voltages are adjustable down to 0.6V. Standard supervisory features include Soft-start, Power Good, output Under-voltage and Over-voltage protection, Under-voltage Lockout, and chip Enable.
