STR-W6251D General Description
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.
STR-W6251D Maximum Ratings
- 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
