2005.07.5 - Sanken Electric Co. are proud to introduce their new STR-A6200 Series Low Power Off-line SMPS Primary Switcher. This state-of-the-art DIP-8 IC boasts the following outstanding features:
- PWM operational frequency jittering
The frequency jittering function enables cost reduction of EMI noise filtering circuit by suppressing EMI noise. The center frequency of PWM operation is set to 50 KHz, and the frequency jittering provides variation of +/–2KHz, which is adjustable by the external capacitor.
- Over Load Protection with the integrated timer (Auto restart)
The IC integrates the delay timer circuit to trip the over load protection, which excludes necessity of any external component for that purpose, and enables reductions of both and PCB design area.
- Over current protection with constant current operation
Constant output current operation is realized by simply adding two external resistors.
- Auto burst standby operation
Reduces standby input less than 100mW at zero load and AC264V
- Soft start
Reduces stress to the integrated power MOSFET during startup
- Less transformer's audible noise during the bust mode operation
- Start-up circuit
Thanks to the proprietary 900V BCD process, the integrated startup circuit, which is connected to the internal MOSFET's drain to power the control circuit, simplifies the peripheral circuit design and improves the system efficiency.
- Current Mode Feedback Control
- Leading Edge Blanking
Avoids operational malfunctioning resulted by surge current during turn-on period, and eliminates necessity of a surge filtering circuit.
- Avalanche energy guaranteed MOSFET
Simplifies a design of surge absorption circuit, and does not require derating to the breakdown voltage.
- Various protections
Over current protection (OCP) ……… Pulse By Pulse
Over load protection (OLP) ………… Auto Restart
Over voltage protection (OVP) ……… Latch
Thermal shut down (TSD)…………… Latch
Advanced applications include the following:
- Battery charger - Cellular phone, Digital camera, Video camera, Electrical shaver, Emergency lighting system, etc.
- Standby power supply - CRT-TV, Projection-TV, LCD-TV, PDP-TV, Desk Top PC, LBP, Audio system, etc.
- Small power S.M.P.S. - Including jet printer, DVD player/recorder, VCR, CD player, Set top box, Air conditioner, refrigerator, washing machine, dish washer, etc.
