Switching Regulators Reduce External Component Count
Auto-Burst Mode Operation
Bias-Assist
AC Input-Independent OCP
Allegro MicroSystems, Inc. announces its STR-W6250D series of off-line switching regulators that are targeted at the consumer and industrial markets. The series is composed of current-mode PWM ICs that incorporate both controller chips made by a high-voltage proprietary BCD process and avalanche-guaranteed MOSFETs. These elements allow power supply system designs that are reliable and simple with fewer peripheral components. These ICs also provide auto-burst mode operation, lowering input power requirements at light loads and improving efficiency over the entire load range and universal input range. Functional integrations include frequency jittering for EMI noise reduction, bias-assist, externally activated shutdown protection, slope compensation for continuous mode operation and AC input-independent OCP to minimize the deliverable output power dependency on the AC input.
