UTC3844E-线性集成电路

DESCRIPTION

The UTC3844D/E provides the necessary features to
implement off-line or DC to DC fixed frequency current mode
control schemes with a minimal external parts count.
Internally implemented circuits include under-voltage lockout
featuring start up current less than 0.5mA,a precision
reference trimmed for accuracy at the error amp input, logic
to insure latched operation, a PWM comparator which 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 in the

off state.

FEATURES
Optimized for off-line and DC to DC converts
Low start up current(<0.5mA)
Automatic feed forward compensation
Pulse-by-Pulse current limiting
Enhanced load response characteristics
Under-voltage lockout with hysteresis
Double pulse Suppression
High current totem pole output
Internally trimmed bandgap reference
500kHz operation
Low Ro error amp
