The LM2657 is a dual synchronous buck regulator controller with input voltage range from 4.5V to 28V. It features synchronous dual-channel interleaved switching, Forced-PWM or Pulse-Skip modes, lossless bottom-side FET current sensing, adaptive duty cycle clamp, high current N-channel FET drivers, low shutdown supply current, reference voltage accurate to within ±1.5%, output voltage adjustable down to 0.6V, Power Good flag and chip enable, under-voltage lockout, over-voltage/under-voltage protection, soft-start, and adjustable switching frequency from 200kHz to 500kHz. It comes in a 28-Pin TSSOP package. The device requires only N-channel FETs for both the upper and lower positions of each stage and 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 achieved by sensing the voltage drop across the bottom FET. The adaptive duty cycle clamping technique reduces peak currents under abnormal load conditions. The two independently programmable outputs switch 180° out of phase (interleaved switching) reducing the input capacitor and filter requirements. Standard supervisory and control features include Soft-start, Power Good, output Under-voltage and Over-voltage protection, Under-voltage Lockout, and chip Enable.
