S-8357 PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER

S-8355/56/57/58 Series STEP-UP, SUPER-SMALL PACKAGE, 600 kHz, PWM CONTROL or www.sii-ic.com PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER © SII Semiconductor Corporation, 2002-2015 Rev.8.1_01 The S-8355/56/57/58 Series is a CMOS step-up switching regulator controller which mainly consists of a reference voltage source, an oscillation circuit, an error amplifier, a phase compensation circuit, a PWM control circuit (S-8355/57 Series) and a PWM/PFM switching control circuit (S-8356/58 Ser.

S-8357 Features

* a PWM/PFM switching controller that can switch the operation to a PFM controller with a duty ratio is 15% under a light load to prevent a decline in the efficiency due to the IC operating current.

* Features

* Low voltage operation : Startup at 0.9 V min. (IOUT = 1 mA) guaranteed
