UC2844D8 - PWM Controller, 25V-12V supply, 450 kHz

UC2844D8 - PWM Controller, 25V-12V supply, 450 kHz

Descrição geral do produto

The UC2844D8 is a current-mode Pulse Width Modulation (PWM) Controller 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 1mA, 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.

Low start-up current
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
Low RO Error amplifier
Green product and no Sb/Br
