DescriptionThe UC2526ADWTRG4 is one member of the UC2526A family which is designed as the improved-performance pulse-width modulator that retains the protective features of under-voltage lockout, soft-start, digital current limiting, double pulse suppression logic, and adjustable deadtime with the help of some improvements (include the incorporation of a precision, band-gap reference generator, reduced overall supply current, and the addition of thermal shutdown protection).
Features of the UC2526ADWTRG4 are:(1)reduced supply current; (2)oscillator frequency to 600kHz; (3)precision band-gap reference; (4)7 to 35V operation; (5)dual 200mA source/sink outputs; (6)minimum output cross-conduction; (7)double-pulse suppression logic; (8)under-voltage lockout; (9)programmable soft-start; (10)thermal shutdown; (11)TTL/CMOS compatible logic ports; (12)5 volt operation (VIN = VC = VREF = 5.0V).
The absolute maximum ratings of the UC2526ADWTRG4 can be summarized as:(1)Input Voltage (+VIN): +40 V;(2)Collector Supply Voltage (+VC): +40 V;(3)Logic Inputs: -0.3 V to +5.5 V;(4)Analog Inputs: -0.3 V to +VIN;(5)Source/Sink Load Current (each output): 200 mA;(6)Reference Load Current: 50 mA;(7)Logic Sink Current: 15 mA;(8)Power Dissipation at TA = +25°C: 1000 mW;(9)Power Dissipation at TC = +25°C: 3000 mW;(10)Operating Junction Temperature: +150°C;(11)Storage Temperature Range: -65°C to +150°C;(12)Lead Temperature (soldering, 10 seconds): +300°C.
The electrical characteristics of this device UC2526ADWTRG4 can be summarized as:(1)Output Voltage: 4.95 to 5.05 V;(2)Line Regulation: 2 to 10 mV;(3)Load Regulation: 5 to 20 mV;(4)Temperature Stability: 15 to 50 mV;(5)Total Output Voltage Range: 4.90 V to 5.10 V;(6)Short Circuit Current: 25 to 100 mA;(7)Initial Accuracy: ±3 % to ±8 %;(8)Voltage Stability: 0.5 to 1 %;(9)Temperature Stability: 2 to 6 %;(10)Minimum Frequency: 1 Hz.
