Introduction

The TD8303X is a monolithic synchronous buck regulator. The device integrates low Rds(on) MOSFETS that provide 3A of continuous load current over a wide operating input voltage of 4.5V to 30V. Current Mode Control provides fast transient responses and cycle-by-cycle current limiting. An adjustable soft-start prevents inrush current at turn-on, and the supply current drops below 3μA in shutdown mode. It integrates Input Under-Voltage Protection, Over-Voltage Protection, Output Over-Voltage Protection and a 160°C Thermal Protection Threshold with 15°C hysteresis. This device, available in ESOP-8 package, provides a very compact system solution with a minimal number of external components. The TD8303x is a single channel, constant frequency, current mode step-down switching regulator for 30V, 3A application. It regulates 4.5V to 30V down an output voltage as low as 0.8V, and supplies up to 3A of load current.
