SLUS557G – MARCH 2003 – REVISED DECEMBER 2016 UC2802x Economy High-Speed PWM Controller
1 Features 1 Targeted for cost-effective solutions with minimal
external components. UC2802x devices include an
oscillator, a temperature compensated reference, a
wide bandwidth error amplifier, a high-speed currentsense comparator, and high-current, active-high,
totem-pole outputs to directly drive external
MOSFETs. Peak Current Mode, Average Current Mode, or
Voltage Mode (With FeedForward) Control
