Product Summary
The ncp1582dr2g is a low cost PWM controller. The ncp1582dr2g is designed to operate from a 5 V or 12 V supply. The ncp1582dr2g is capable of producing an output voltage as low as 0.8 V. This 8-pin device of the ncp1582dr2g provides an optimal level of integration to reduce size and cost of the power supply. Features include a 0.7 A gate driver and an internally set 350 kHz and a 300 kHz oscillator. The ncp1582dr2g also incorporates an externally compensated transconductance error amplifier and a programmable soft-start function. Protection features include short circuit protection (SCP) and under voltage lockout (UVLO). The ncp1582dr2g comes in an 8-pin SOIC package. The applications of the ncp1582dr2g include Graphics Cards, Desktop Computers, Servers / Networking, DSP and FPGA Power Supply, DC-DC Regulator Modules.
