AN8014S

Voltage regulators AN8014S Step-down, step-up, or inverting DC-DC converter control IC s Overview The AN8014S is a single-channel PWM DC-DC converter control IC. This IC can provide any one output type from among step-down, step-up and inverting output. Allowing n-channel power MOSFET direct driving, the AN8014S is ideal for high-efficiency power supplies. 10.1±0.3 16 9 Unit: mm 4.2±0.3 6.5±0.3 (0.15) 0.3 (0° to 10°) s Features Wide operating supply voltage range (3.6 V to 34 V) (The voltage is limited within a range between 3.6 V and 17 V if it is connected to a step-down volt1.27 (0.605) 0.40±0.25 age circuit.)
