About This Product

■PRC (Pulse Ratio Control) method

ON time control method with fixed OFF time. Low noise, suitable for small to medium power applications.

■Summary

This product is a power IC for PRC (*) type switching power supplies that incorporates a power MOSFET and a current mode PRC (*) control IC in one package. *PRC (Pulse Ratio Control) Control method with fixed OFF time and ON time control (our name) A low-profile package with a creepage distance of 4 mm or more between high voltage and low voltage (lead terminals on the board) is used. The control unit has a built-in startup circuit and standby function, allowing for low power consumption and low standby power. With its extensive protection functions, you can easily configure a cost-effective power system with fewer components.

■Application

・For standby power supply ・For white goods ・For digital home appliances ・For OA equipment ・For industrial equipment ・For communication equipment Switching power supplies for various electronic devices such as

■Main specifications

・MOSFET 650V (MIN), 2.8Ω (MAX) ・tOFF (fixed) 8µs (TYP)

■Features

・SIP8L package (our name: STA8L, 2.54 pitch) Creepage distance between high voltage and low voltage 4 mm or more (lead terminal on board) Height from board 12 mm or less ・Current mode type PRC control ・Built-in auto standby function (No-load input power PIN <40mW, low power consumption supported) ・Built-in startup circuit (reduces power consumption during standby and reduces external components) ・Built-in auto bias function (operation stabilization during burst oscillation operation) ・Built-in leading edge blanking function ・Guaranteed avalanche energy tolerance due to 2-chip structure (surge absorption circuit can be simplified) ・Protection functions (Overcurrent protection (OCP): Pulse-by-pulse, Overload protection (OLP): Heat reduction/automatic recovery during overload, Overvoltage protection (OVP): Latch-off (*), Thermal protection (TSD) : Latch off (*) ) *Latch-off: Latch-off is an operation that continues to stop oscillation for protection.
