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 selects single-ended or
push-pull operation
• Operating temperature range : -25℃ ~ +85℃
• Halogen-Free Package is Available
• High Level ESD Protection : 400V(MM), 4KV(HBM)
◈ Application
