STR-A6000_15 Datasheet, PDF (1/28 Pages) Sanken electric – Off-Line PWM Controllers with Integrated Power MOSFET

Off-Line PWM Controllers with Integrated Power MOSFET
STR-A6000 Series
General Descriptions
The STR-A6000 series are power ICs for switching
power supplies, incorporating a MOSFET and a current
mode PWM controller IC.
The low standby power is accomplished by the
automatic switching between the PWM operation in
normal operation and the burst-oscillation under light
load conditions. The product achieves high
cost-performance power supply systems with few
external components.
Features
 Current Mode Type PWM Control
 Brown-In and Brown-Out function
 Auto Standby Function
No Load Power Consumption < 25mW
 Operation Mode
Normal Operation ----------------------------- PWM Mode
Standby ---------------------------- Burst Oscillation Mode
 Random Switching Function
 Slope Compensation Function
 Leading Edge Blanking Function
 Bias Assist Function
 Audible Noise Suppression function during Standby
mode
 Protections
・Overcurrent Protection (OCP)*; Pulse-by-Pulse,
built-in compensation circuit to minimize OCP point
variation on AC input voltage
・Overload Protection (OLP); auto-restart
・Overvoltage Protection (OVP); latched shutdown
・Thermal Shutdown Protection (TSD); latched shutdown
*STR-A60××HD has two types OCP

* The output power is actual continues power that is measured at
50 °C ambient. The peak output power can be 120 to 140 % of the
value stated here. Core size, ON Duty, and thermal design affect
the output power. It may be less than the value stated here.
Applications
 Low power AC/DC adapter
 White goods
 Auxiliary power supply
 OA, AV and industrial equipment
