产品概述
The TL284x and TL384x series of control integrated circuits provide the features that are
necessary to implement off-line or DC-to-DC fixed-frequency current-mode control schemes, with a
minimum number of external components. Some of the internally implemented circuits are an
undervoltage lockout (UVLO), featuring a start-up current of less than 1 mA, and a precision
reference trimmed for accuracy at the error amplifier input. Other internal circuits include logic
to ensure latched operation, a pulse-width modulation (PWM) comparator (that also provides
current-limit control), and a totem-pole output stage designed to source or sink high-peak current.
The output stage, suitable for driving N-channel MOSFETs, is low when it is in the off
state.
