资料介绍

LMR62421是TI推出的SIMPLE SWITCHER® 24Vout, 2.1A Step-Up Voltage Regulator in。 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 and low side gate drivers for the four external brige 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 startup 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,
