Description
- 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.
- FEATURES
- • 7V to 40V operation
- • 5V reference trimmed to ±1%
- • 100Hz to 400KHz oscillator range
- • Excellent external sync capability
- • Dual 100mA output transistors
- • Wide current limit common mode range
- • DC-coupled toggle flip-flop
- • PWM data latch
- • Undervoltage lockout
- • Full double-pulse suppression logic
- • 60V output collectors
