Overview

Rev.2.0_00 STEP-UP, SUPER-SMALL PACKAGE, PFM CONTROL SWITCHING REGULATOR / SWITCHING REGULATOR CONTROLLER S-8351/8352 Series 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).

Key Features

s.
Low voltage operation : Startup at 0.9 V min. (IOUT = 1 mA) guaranteed.
Low current consumption : During operation 23.2 µA (VOUT = 3.3 V, typ. ) During shutdown 0.5 µA (max. ).
Duty ratio : 50 % / 75 % built-in auto-switching-type PFM control circuit (A, B, and D type) 75 % built-in fixed-type PFM control circuit (C type).
External parts : Coil, capacitor, and diode.
Output voltage : Selectable in 0.1 V steps between 2.0 to 6.5 V (A, B, and C type) S.
