Introduction

AI Translation

A synchronous buck controller with internal MOSFETs packaged in a small 4mmx4mm QFN package. The ER2120QI can support a continuous load of 2A and has a very wide input voltage range. With the switching MOSFETs integrated into the IC, the complete regulator footprint can be very small and provide a much more efficient solution than a linear regulator. The ER2120QI is capable of stand-alone operation or it can be used in a master slave combination for multiple outputs that are derived from the same input rail. Multiple slave channels (up to six) can be synchronized. This method minimizes the EMI and beat frequencies effect with multi-channel operation. The switching PWM controller drives two internal N-Channel MOSFETs in a synchronous-rectified buck converter topology. The synchronous buck converter uses voltage-mode control with fast transient response. The switching regulator provides a maximum static regulation tolerance of ±1% over line, load, and temperature ranges. The output is user-adjustable by means of external resistors down to 0.6V. The output is monitored for undervoltage events. The switching regulator also has overcurrent protection. Thermal shutdown is integrated. The ER2120QI features a bi-directional Enable pin that allows the part to pull the enable pin low during fault detection. POK delay for ER2120QI is 1ms typical (at 500kHz switching frequency).
