UC2526DW

The UC2526DW is a regulating pulse width modulator.The UC2526 is a high performance monolithic pulse width modulator circuit designed for fixed-frequency switching regulators and other power control applications.Included in an 18-pin dual-in-line pack-age are a temperature compensated voltage reference,sawtooth os-cillator,error amplifier, pulse width modulator,pulse metering and setting logic,and two low impedance power drivers.It is characterized for operation from -25°C to +85°C.

Features of the UC2526DW are:(1)8V to 35V Operation;(2)5V Reference Trimmed To ±1%;(3)1Hz To 400kHz Oscillator Range;(4)Dual 100mA Source/Sink Outputs;(5)Digital Current Limiting;(6)Double Pulse Suppression;(7)Programmable Deadtime;(8)Under-Voltage Lockout;(9)Single Pulse Metering;(10)Programmable Soft-Start;(11)Wide Current Limit Common Mode Range;(12)TTL/CMOS Compatible Logic Ports;(13)Symmetry Correction Capability;(14)Guaranteed 6 Unit Synchronization.

The absolute maximum ratings of the UC2526DW can be summarized as:(1)Input Voltage(+V_IN):+40V;(2)Collector Supply Voltage (V_C):+40V;(3)Logic Inputs:0.3V to +5.5V;(4)Analog Inputs:0.3V to +V_IN;(5)Source/Sink Load Current (each output):200mA;(6)Reference Load Current:50mA;(7)Logic Sink Current:15mA;(8)Power Dissipation at T_A = +25°C (Note 2):1000mW;(9)Power Dissipation at T_C = +25°C (Note 2):3000mW;(10)Operating Junction Temperature:+150°C;(11)Storage Temperature Range:65°C to +150°C;(12)Lead Temperature (Soldering, 10 seconds):+300°C.Note 1: Values beyond which damage may occur.Note 2: Consult packaging Section of Databook for thermal limitations and considerations of package.
