natlinear LN2266
The LN2266 is a compact, high efficiency, and low voltage step-up DC/DC converter with an Adaptive Current Mode PWM control loop, includes an error amplifier, ramp generator, comparator, switch pass element and driver in which providing a stable and high efficient operation over a wide range of load currents. It operates in stable waveforms without external compensation. The low start-up input voltage below 0.9V makes LN2266 suitable for 1 to 4 battery cells applications of providing up to 1100mA output current.| Part No. | LN2266 |
