S-8460 Datasheet | Seiko Instruments

Rev.2.0_00 STEP-UP OR DOWN, SINGLE-COIL, PWM CONTROL SWITCHING REGULATOR CONTROLLER The S-8460 is a PWM control CMOS step-up and step-down switching regulator controller which consists of an automatic-selection control circuit for step-up and step-down, a reference voltage circuit, an oscillation circuit, an error amplifier, a phase pensation circuit, etc. The automatic-selection control circuit for step-up and stepdown in PWM control realizes a high performance step-up and stepdown switching regulator operating on one coil. With an external Nchannel power MOS, the S-8460 is ideal for applications requiring high efficiency and a high current output. The S-8460 realizes low...
