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.
