SG1524B/SG2524B/SG3524B
REGULATING PULSE WIDTH MODULATOR
DESCRIPTION
The SG1524B is a pulse width modulator for switching power supplies
which features improved performance over industry standards like the
SG1524. A direct pin-for-pin replacement for the earlier device, it
combines advanced processing techniques and circuit design to provide
improved reference accuracy, and extended common mode range at the
error amplifier and current limit inputs. A DC-coupled flip-flop eliminates
triggering and glitch problems, and a PWM data latch prevents edge
oscillations. The circuit incorporates true digital shutdown for high speed
response, while an undervoltage lockout circuit prevents spurious outputs
when the supply voltage is too low for stable operation. Full double-pulse
suppression logic insures alternating output pulses when the Shutdown
pin is used for pulse-by-pulse current limiting. The SG1524B is specified
for operation over the full military ambient temperature range of -55°C to
125°C. The SG2524B is characterized for the industrial range of -25°C to
85°C, and the SG3524B is designed for the commercial range of 0°C
to 70°C.
