... HIGH EFFICIENCY STEP-UP DC/DC CONVERTER DESCRIPTION The SC46166 is a compact, high efficiency, and low voltage step-up DC/DC converter, includes an error amplifier, ramp generator, current comparator, slope compensation, current sense and driver. Peak current mode PWM control with internal compensation reduces external parts count and provides a stable and high efficient operation over a wide range of load currents ...

... The SC46166 is a 500kHz, asynchronous boost converter housed in a compact package, includes a voltage reference, error amplifier, ramp generator, current comparator, slope compensation, current sense and driver. The low start-up function allows SC46166 operating from an input voltage below 1V, 0.85V typically at V HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http://www ...

... COMPONENT SELECTION Inductor Selection The SC46166 can utilize small surface mount and chip inductors due to its fast 500kHz switching frequency. Typically, a 4.7μH inductor is recommended for most applications. Larger values of inductance will allow greater output current capability by reducing the inductor ripple current. Increasing the inductance above will also increase size ...

... Operating at light loads, a additional feed forward capacitor may be required (for example C1 in the Figure 1)to maintain acceptable output voltage ripple. For all the three capacitors above, X5R and X7R dielectric materials are preferred, for their ability to maintain capacitance over wide voltage and temperature ranges.
