Stmicroelectronics (SG3525AN) PWM Controller Dual, 35V-8V supply, 400 kHz

PWM Controller Dual, 35V-8V supply, 400 kHz, 5.1V/500mA out, DIP-16 Product Overview The SG3525AN is a regulating pulse width Modulator IC is designed to offer improved performance and lowered external parts count when used in designing all types of switching power supplies. The on-chip 5.1V reference is trimmed to ±1% and the input common-mode range of the error amplifier includes the reference voltage eliminating external resistors. A single resistor between the CT and the discharge terminals provide a wide range of dead time adjustment. This device also features built-in soft-start circuitry with only an external timing capacitor required. A shutdown terminal controls both the soft-start circuitry and the output stages, providing instantaneous turn OFF through the PWM latch with pulsed shutdown, as well as soft-start recycle with longer shutdown commands. Separate oscillator sync terminal Adjustable dead-time control Internal soft-start Pulse-by-pulse shutdown Input undervoltage lockout with hysteresis Latching PWM to prevent multiple pulses Dual source/sink output drivers Product Information Input Voltage: 35V Output Voltage: 5.1V Output Current: 500mA Supply Voltage Min: 8V Supply Voltage Max: 35V Controller IC Case Style: DIP No. of Pins: 16Pins Frequency: 400kHz Operating Temperature Min: 0°C Operating Temperature Max: 70°C Product Range: - MSL: MSL 1 - Unlimited
