Additional features include an error amplifier with band-
width in excess of 7MHz, a 5V reference, provisions for
soft-starting, and flexible ramp generation and slope com-
pensation circuitry.
These devices are available in 20-pin DIP, 28-pin
“bat-wing” SOIC and 28 lead power PLCC plastic pack-
ages for operation over both 0°C to 70°C and –25°C to
+85°C temperature ranges; and in hermetically sealed
cerdip, surface mount, and ceramic leadless chip carrier
packages for –55°C to +125°C operation.
