Description

The LM2676T-ADJ is a kind of voltage regulator. It is a monolithic integrated circuit to provide all of the active functions for a stepdown (buck) switching regulator. It is an adjustable output version. The typical applications include simple to design, high efficiency (>90%) step-down switching regulators, efficient system pre-regulator for linear voltage regulators and battery chargers.

There are some features of LM2676T-ADJ as follows: (1) efficiency up to 94%; (2) simple and easy to design with (using off-the-shelf external components); (3) 150 m DMOS output switch; (4) 50A standby current when switched OFF; (5) ±2% maximum output tolerance over full line and load conditions; (6) wide input voltage range: 8 to 40 V; (7) 260 KHz fixed frequency internal oscillator; (8) -40 to +125 operating junction temperature range.

What comes next is the absolute maximum ratings of LM2676T-ADJ. (1): input supply voltage is 45 V; (2): ON/OFF pin voltage is from -0.1 to 6 V; (3): switch voltage to ground is from -1 to VIN V; (4): boost pin voltage is VSW+8 V; (5): feedback pin voltage is from -0.3 to 14 V; (6): power dissipation is internally limited; (7): ESD is 2 kV; (8): storage temperature range is from -65 to +150; (9): soldering temperature of wave is 260 for 4 sec, of infrared is 240 for 10 sec and of vapor phase is 219 for 75 sec.
