SG1525AJ/12875

The SG1525AJ/12875 is designed as one kind of regulating pulse width modulator device that features built-in soft-start circuitry with only a timing capacitor required externally and NOR logic, giving a LOW output for an OFF state. Features of this device are:(1)8V to 35V operation; (2)5.1V reference trimmed to ±1%; (3)100Hz to 500KHz oscillator range; (4)Separate oscillator sync terminal; (5)Adjustable deadtime control; (6)Internal soft-start; (7)Input under-voltage lockout; (8)Latching P.W.M. to prevent multiple pulses; (9)Dual source/sink output drivers.

The absolute maximum ratings of the SG1525AJ/12875 can be summarized as:(1)Supply Voltage (+VIN): 40 V;(2)Collector Supply Voltage (Vc): 40 V;(3)Logic Inputs: -0.3V to 5.5V;(4)Analog Inputs: -0.3V to VIN;(5)Output Current, Source or Sink: 500 mA;(6)Reference Load Current: 50 mA;(7)Lead Temperature (Soldering, 10 seconds): 300°C;(8)Storage Temperature Range: -65°C to 150°C;(9)Oscillator Charging Current: 5 mA;(10)Operating Junction Temperature Range: 150°C.
