PRODUCTION DATA
The LV2862 device is a 60-V, 600-mA, step-down (buck) regulator. The buck regulator has a very low quiescent current during light load to prolong the battery life.
The LV2862 improves performance during line and load transients by implementing a constant frequency, current mode control which reduces output capacitance and simplifies frequency compensation design. The LV2862 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 a UVLO circuit and turns the high-side MOSFET off when the boot voltage falls below a preset threshold. The LV2862 can operate at high duty cycles because of the boot UVLO and refresh the wimp FET. The output voltage can be stepped down to as low as the 0.8 V. Internal soft start is featured to minimize inrush currents.
