TEXAS INSTRUMENTS LM25037MT 双模控制器, PWM, 交替输出, 14V-8V电源, 200 kHz, 9.75V/100mA输出, TSSOP-16
The is a PWM Controller contains all the features necessary to implement balanced double-ended power converter topologies, such as push-pull, half-bridge and full-bridge. These double-ended topologies allow for higher efficiencies and greater power densities compared to common single-ended topologies such as the flyback and forward. The LM25037 can be configured for either voltage mode or current-mode control with minimum external components. Two alternating gate drive outputs are provided, each capable of 1.2A peak output current. It can be configured to operate directly from the input voltage rail over an ultra-wide range of 5.5 to 75V. Additional features include programmable maximum duty cycle limit, line undervoltage lockout, cycle-by-cycle current limit and a hiccup mode fault protection with adjustable timeout delay, soft-start and a 2MHz capable oscillator with synchronization capability, precision reference and thermal shutdown.
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
