DESCRIPTION
The IP1525A and IP1527A families of PWM switching regulator control circuits offer improved performance and lower
parts count when used in designing switching power supplies. Included are 5.1 volt reference, error amplifier, adjustable
dead-time oscillator with synchronisation capability, latched PWM comparator, totem-pole output drivers, shutdown, soft
start, and undervoltage lockout.
The IP1525A and IP1527A differ only in output phasing. The IP1525A output is low when “off”, while the IP1527A
output is high when “off”.
