Monolithic Power Systems HR1002GS

The HR1002 is an enhanced LLC controller that provides robust adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP), as well as improved functional surge performance. This is ensured by keeping the outputs off while sensing the dV/dt current of the half-bridge switching node. The HR1002 incorporates capacitive mode protection, which prevents potentially destructive capacitive mode switching if the output is shorted or is severely overloaded.

DESCRIPTION

ADTA automatically inserts a dead time between the two complimentary gate outputs. ADTA simplifies the design and provides lower EMI, as well as higher efficiency. This feature protects the MOSFET during abnormal conditions to provide a robust converter. The HR1002 has a configurable oscillator that sets both the maximum and minimum switching frequencies. To prevent excessive inrush current, it starts up at a configured maximum switching frequency and decays until the control loop takes over. The HR1002 enters a controlled burst mode under light-load conditions to minimize power consumption and tighten the output regulation. Full protection features include two-level overcurrent protection (OCP) with external latched shutdown, auto-recovery, brown-in and brownout, capacitive mode protection (CMP), and over-temperature protection (OTP). The HR1002 requires minimal external components, and is available in an SOIC-16 package.
