STEP-UP, SUPER-SMALL PACKAGE, PFM CONTROL SWITCHING REGULATOR / SWITCHING REGULATOR CONTROLLER

The S-8351 S-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 A protection circuit turns off the built-in MOS FET when the voltage at the CONT pin exceeds the limit to prevent it from being damaged. In addition to the above features, the small package and low current consumption, makes the S-8351 Series ideal for applications such as the power supply unit of portable equipment. The S-8352 Series, which features an external Transistor is suitable for applications requiring a high output current. By Seiko Instruments Inc.
