Texas Instruments UC3846DW 电源控制器
TEXAS INSTRUMENTS UC3846DW Current Mode PWM, 40V-8V supply, 500 kHz, 5.1V/500A out, SOIC-16
TEXAS INSTRUMENTS
The UC3846DW is a current-mode Pulse Width Modulation (PWM) Controller provides all of the necessary features to implement fixed-frequency, current-mode control schemes while maintaining a minimum external parts count. The superior performance of this technique can be measured in improved line regulation, enhanced load response characteristics and a simpler, easier-to-design control loop. Topological advantages include inherent pulse-by-pulse current limiting capability, automatic symmetry correction for push-pull converters and the ability to parallel while maintaining equal current sharing. The protection circuitry includes built-in under-voltage lockout and programmable current limit, in addition to soft-start capability. A shutdown function is also available, which can initiate either a complete shutdown with automatic restart or latch the supply off. Other features include fully-latched operation, double-pulse suppression. Automatic feed forward compensation Programmable pulse-by-pulse current limiting Automatic symmetry correction in push-pull configuration Enhanced load response characteristics Parallel operation capability for modular power systems Differential current sense amplifier with wide common mode range Double-pulse suppression 500mA (Peak) Totem-pole outputs ±1% Band gap reference Undervoltage lockout Soft-start capability Shutdown terminal Error amplifier Green product and no Sb/Br Input Voltage: 15V Output Voltage: 5.1V Output Current: 500mA Supply Voltage Min: 8V Supply Voltage Max: 40V Controller IC Case Style: SOIC No. of Pins: 16Pins 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: MSL 2 - 1 year Supply Voltage Range: 8V to 40V SVHC: No SVHC (15-Jun-2015) Digital IC Case Style: SOIC Find similar products grouped by common attribute
