S-8351/8352 Series www.ablicinc.com © ABLIC Inc., 2002-2010 STEP-UP, BUILT-IN / EXTERNAL FET PFM CONTROL SWITCHING REGULATOR / SWITCHING REGULATOR CONTROLLER Rev.3.0_02 The S-8351/8352 Series is a CMOS step-up switching regulator controller which mainly consists of a reference voltage source, an oscillation circuit, a comparator and PFM control circuit. The PFM control circuit allows the duty ratio to be automatically switched according to the load (at light load : 50%, at high output current : 75%), enabling products with a low ripple over a wide range, high efficiency, and high output current (A, B, and D type). Products with a fixed duty ratio of 75% are also available (C type). The S-8351 Series can configure a step-up switching regulator with an external coil, capacitor, and diode.
