LV5066V

Ordering number : ENA2012 Bi-CMOS IC LV5066V Overview Low power consumption and high efficiency Step-down Switching Regulator Controller LV5066V is 1ch step-down switching regulator. The operation current is about 80μA, and low power consumption is achieved. Functions • 1ch diode rectification controller IC • Maximum value of light load mode current is 80μA. • Built-in OCP circuit with P-by-P method • When P-by-P is generated continuously, it shifts to the HICCUP operation. • If connect C-HICCUP to GND pin, then latch-off when over current. • The oscillatory frequency can be set by the external pin. The oscillatory frequency is 300 kHz to 2.2MHz • Built-in UVLO, TSD • Synchronous driving with external signal Specifications Parameter Input voltage Maximum Ratings at Ta = 25°C Symbol VIN max Pd max Topr Tstg Specified substrate *1 Conditions Ratings 22 0.74 -40 to +85 -55 to +150 Unit V W ˚C ˚C Allowable power dissipation Operating temperature Storage temperature *1: Specified substrate 114.3mm×76.1mm×1.6mm3 glass-epoxy Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded.
