产品介绍
Texas Instruments UC3843AN 电源控制器
TEXAS INSTRUMENTS UC3843AN Current Mode PWM, 25V-12V supply, 500 kHz, 15V/1A out, DIP-8
TEXAS INSTRUMENTS
The UC3843AN is a Current Mode PWM Controller optimized for off-line and DC to DC converters. Providing the necessary features to control current mode switched mode power supplies, this controller has the following improved features. Start up current is guaranteed to be less than 0.5mA. Oscillator discharge is trimmed to 8.3mA. During under-voltage lockout, the output stage can sink at least 10mA at less than 1.2V for VCC over 5V. Optimized for off-line and DC to DC converters Low start up current ( Trimmed oscillator discharge 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 amp Green product and no Sb/Br Input Voltage: 25V Output Voltage: 15V 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
