LN2262 Super-Small Package PWM Control Step-up Switching Regulator ■ General Description The LN2262 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. LN2262 can provide 1100mA output current when input voltage above 3.5V. Besides, the 21µA low quiescent current together with high efficiency maintains long battery lifetime. The output voltage is set with two external resistors. Both internal 2.5A switch and driver for driving external power devices (NMOS or NPN) are provided.
