TEXAS INSTRUMENTS LM5045MH/NOPB 控制器, 全桥, 100V-14V电源, 2 MHz, TSSOP-28
The is a Pulse Width Modulated PWM Controller contains all of the features necessary to implement full-bridge topology power converters using either current-mode or voltage mode control. This device is intended to operate on the primary side of an isolated DC-DC converter with input voltage up to 100V. This highly integrated controller-driver provides dual 2A high-side and low-side gate drivers for the four external bridge MOSFETs plus control signals for the secondary-side synchronous rectifier MOSFETs. External resistors program the leading and trailing edge dead-time between the main and synchronous rectifier control signals. Intelligent start-up of the synchronous rectifiers allows monotonic turn-on of the power converter even with pre-bias load conditions. Additional features include cycle-by-cycle current limiting, hiccup mode restart, programmable soft-start, synchronous rectifier soft-start and a 2MHz capable oscillator.
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.
