STR-W6252D

• Overcurrent protection (OCP) with ac input voltage compensation function; no additional peripheral circuits requiredinimizes dependency of OCP on ac input
• Overload protection (OLP) with integrated timer reduces power stress (temperature rise) at overload condition, requires no peripheral components
• Avalanche-guaranteed MOSFET improves device capability of withstanding excess surge voltage, providing a simple surge absorber circuit without breakdown voltage derating
• Start-up circuit eliminates the need for a start-up resistor, and helps to reduce input power consumption
• Bias Assist function improves start-up performance by selfbiasing the VCC pin, and allows a use of a small value VCC capacitor, resulting in improved response to overvoltage conditions
• Very low current consumption in nonoperating (UVLO) state: ICC(off) = 5 µA (typical) at VCC = 13.8 V
• Slope compensation circuit stabilizes operation, preventing interference from subharmonics
• Leading Edge Blanking
• Various protections:
  • Overcurrent Protection (OCP), pulse-by-pulse sensing
  • Overload Protection (OLP), auto restart after certain duration
  • External Latch Protection (ELP), latched
  • Overvoltage Protection (OVP), latched
  • Thermal Shut Down (TSD), latched
• Externally-activated shut down protection (ELP) for emergency system shut down
• Auto-Burst Standby function (pin < 0.1 W at zero output load condition)
• TO-220 full-molded package with 6 pins

The STR-W6200D series are current-mode PWM ICs that incorporate controller chips. These devices are manufactured using a proprietary high-voltage BCD process, and avalancheguaranteed MOSFETs. These elements allow power supply systems designs that are highly reliable and simple, with fewer peripheral components. These ICs also provide Auto-Burst mode operation, which lowers input power requirements at light loads, and improves efficiency over the entire load range and universal-input range.

• TV set top box
• LCD PC monitor, LCD TV
• Printer, scanner
• General consumer, PC, and industrial applications requiring SMPS power supply with standby mode
