DESCRIPTION
The SG1525A/1527A series of pulse width modulator integrated circuits are designed to offer improved performance and lower external parts count when used to implement all types of switching power supplies. The on-chip +5.1 volt reference is trimmed to ±1% initial accuracy and the input common-mode range of the error amplifier includes the reference voltage, eliminating external potentiometers and divider resistors.

FEATURES
• 8V to 35V operation
• 5.1V reference trimmed to ±1%
• 100Hz to 500KHz oscillator range
• Separate oscillator sync terminal
• Adjustable deadtime control
• Internal soft-start
• Input undervoltage lockout
• Latching P.W.M. to prevent multiple pulses
• Dual source/sink output drivers
