KB33 - Brand New IC Chips
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
General Description
The KB3301 is a small, 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 0.8V makes KB3301 suitable for 1 to 4
battery cells applications of providing up to 300mA output current. The 500KHz
high switching rate minimized the size of external components. Besides, the
14µA low quiescent current together with high efficiency maintains long
battery lifetime.
The KB3301 is available in small package SOT-26 and SOT89-5
