Texas Instruments UC3844N 电源控制器
TEXAS INSTRUMENTS UC3844N PWM Controller, 30V-10V supply, 450 kHz, 13.5V/1A out, DIP-8
TEXAS INSTRUMENTS
The UC3844N is a Current Mode PWM Controller optimized for off-line and DC to DC converters. This device 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. Optimized for off-line and DC to DC converters 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 Green product and no Sb/Br Input Voltage: 25V Output Voltage: 13.5V Output Current: 1A Supply Voltage Min: 12V Supply Voltage Max: 25V Controller IC Case Style: DIP No. of Pins: 8Pins Frequency: 450kHz Operating Temperature Min: 0°C Operating Temperature Max: 70°C Packaging: Each Product Range: - Automotive Qualifications Standard: - Power Dissipation Pd: 1 W MSL: - Supply Voltage Range: 12V to 25V SVHC: No SVHC (15-Jun-2015) Digital IC Case Style: DIP Find similar products grouped by common attribute
