SJ7500P

Semiconductor SJ7500/P Pulse Width Modulation ◈ Description The SJ7500 is a monolithic integrated circuit which includes all the necessary building blocks for the design of pulse width modulate(PWM) switching power supplies, including push-pull, bridge and series configuration. The precision of voltage reference is improved up to ±1% through trimming and this provides a better output voltage regulation. The device can operate at switching frequencies between 1KHz and 300KHz and output voltage up to 23V. The SJ7500 is specified over an operating temperature range of -25℃~+85℃. ◈ Features ◈ Package Type Internal Regulator Provides a Stable 5V Reference Supply Trimmed to ±1% Accuracy Uncommitted output transistors capable of 200mA source or sink Internal protection from double pulsing of out-puts with narrow pulse widths or with supply voltages below specified limits Easily synchronized to other circuits Dead time control comparator Output control ...
