General Description

GDMT01-A is a high accuracy, high integration DCM primary side Feed (PSR) switching power supply IC, used in off-line low power converter.Built-in power BJT, can be further reduce the system cost.

GDMT01-A built-in patented“ NC-Cap/PSR-II ”

Control technology , eliminating the external compensation or filter capacitance.Built in the line loss Compensation function, can compensate the output voltage under constant voltage mode.Use the multimode Control technology, to improve system efficiency, reliability, and light load Rate.

GDMT01-A integrated with the patent "audio noise elimination" control technology ,realize the light load working

. built-in patented "Rapid dynamic response technology"

Meet the demand of USB charger. Patented "zero voltage on-load Start "control technology , implement start with full load and 0 v output . Intelligent short circuit protection function, can be in the system of the leakage inductance of the transformer Time, output short circuit can protect.

GDMT01-A integrates the FB short circuit protection function, under voltage lock , VDD over-voltage protection, soft start, cycle-by-cycle current limiting, Pin floated protection, VDD clamping GDMT01-A .Supply SOP-7 package.
