Introduction

AI Translation

The LV2841/2 device is a 40V, 300mA/600mA, step-down (buck) converter. The buck regulator has a very low quiescent current during the light load to prolong the battery life. For LV2841/2, to improve performance during line and load transients it implements a constant frequency, current mode control which reduces output capacitance and simplifies frequency compensation design. Two switching frequency options, 1.1MHz and 2.1MHz, are available, thus smaller inductor and capacitor can be used. The LV2841/2 reduces the external component count by integrating the boot recharge diode. The bias voltage for the integrated high side MOSFET is supplied by a capacitor on the CB to SW pin. The boot capacitor voltage is monitored by an UVLO circuit and will turn the high side MOSFET off when the boot voltage falls below a preset threshold. The LV2841/2 can operate at high duty cycles because of the boot UVLO and refresh wimp FET. The output voltage can be stepped down to as low as the 0.8V reference. Internal soft start is featured to minimize inrush currents.
