SG1826-042B

The SG1826-042B is designed as one kind of current mode PWM controller device that is specified for operation over the full military ambient temperature range of -55°C to 125°C. And this deivce has under voltage lockout, current limiting circuitry and start-up current of less than 1mA.

Features of the SG1826-042B are:(1)10V to 30V operation; (2)5.1V reference trimmed to ±1%; (3)2 MHz oscillator capability; (4)1.5A peak totem-pole drivers; (5)U.V. lockout with hysteresis; (6)no output driver "float"; (7)programmable softstart; (8)double-pulse suppression logic; (9)wideband low-impedance error amplifier; (10)current-mode or voltage-mode control; (11)wide choice of high-frequency packages.

The absolute maximum ratings of the SG1826-042B can be summarized as:(1)Input Voltage (VIN and VC): 30 V;(2)Digital Input (Clock): 1.5V to 6.0V;(3)Driver Outputs: -0.3V to +1.5V;(4)Source / Sink Output Current Continuous: 0.5 A;(5)Source / Sink Output Current Pulse, 500ns: 2.0 A;(6)Operating Junction Temperature: 150°C;(7)Storage Temperature Range: -65°C to 150°C;(8)Lead Temperature (Soldering, 10 Seconds): 300°C.
