STR-A6151

STR-A6159

regulators specifically designed to satisfy the requirements for increased

integration and reliability in flyback converters. They incorporate a

primary control and drive circuit with avalanche-rated power

MOSFETs. The STR-A6151 features higher switching current and

avalanche-energy ratings and lower on-resistance.

VAC input, or 10 to 12 watts for a universal (85 to 264 VAC) input,

these devices can be used in a range of applications, from DVD and

VCR players to ac adapters for cellular phones and digital cameras. An

auto-standby function reduces power consumption at light load, while

multiple protections, including the avalanche-energy guaranteed

MOSFET, provide high reliability of system design.

esis, overvoltage protection, and thermal shutdown protect the power

supply during the normal overload and fault conditions. Overvoltage

protection and thermal shutdown are latched after a short delay. The

latch may be reset by cycling the input supply. Low start-up current and

a low-power standby mode selected from the secondary circuit completes

a comprehensive suite of features. Both devices are provided in an 8-pin

mini-DIP plastic package.

Always order by complete part number, e.g., STR-A6151 .
