| The Future of Analog IC Technology HR1001 Enhanced LLC Controller with Adaptive Dead Time Control The HR1001 is an enhanced LLC controller which provides new features of adaptive dead time adjustment ADTA and capacitive mode protection CMP . The adaptive dead time adjustment automatically inserts a dead time between the two complimentary gate outputs. This is ensured by keeping the outputs off while sensing the dv/dt current of the half-bridge switching node. The ADTA features easier design, lower EMI, and higher efficiency. HR1001 incorporates anti-capacitive mode protection which prevents potentially destructive capacitive mode switching if the output is shorted or has a severe over load. This feature protects the MOSFET during abnormal condition, making the converter robust. HR1001 has a programmable oscillator that sets both the maximum and minimum switching frequencies. It starts up at a programmed maximum switching frequency and decays until the control loop takes over to prevent excessive inrush current. HR1001 enters a controlled burst-mode operation at light-load to minimize the power consumption and tighten output regulation. HR1001 provides rich protection features which include two-level OCP with external latch shutdown, auto-recovery, brown in/out, CMP, and OTP, improving converter design safety with minimal extra components. • Adaptive dead-time adjustment • Capacitive mode protection • 50% Duty Cycle, Variable Frequency Control For Resonant Half-Bridge Converter • 600V High-Side Gate Driver with Integrated Bootstrap Diode with High dv/dt immunity • High-Accuracy Oscillator • Operates up to 600kHz • Two-Level Over-Current Protection: Frequency-Shift and Latched Shutdown with Programmable Duration Time • Latched Disable Input for Easy Protections • Remote ON/OFF Control and Brown-Out Protection through the BO Pin • Programmable Burst-Mode Operation at Light-Load • Non-Linear Soft-Start for Monotonic Output Voltage Rise • SOIC-16 package • LCD and PDP TVs • Desktop PCs and Servers • Telecom SMPS • AC-DC Adapter, Open-Frame SMPS • Video Game Consoles • Electronic Lighting Ballast All MPS parts are lead-free and adhere to the RoHS directive.

Recommended Operating Conditions 3 Supply Voltage 13V to 15.5V Analog inputs and outputs -0.3V to 6V Operating Junction Temp TJ -40°C to + 125°C Thermal Resistance 4 SOIC16 Notes 1 Exceeding these ratings may damage the device. 2 The maximum allowable power dissipation is a function of the maximum junction temperature TJ MAX , the junction-toambient thermal resistance and the ambient temperature TA. The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD MAX = TJ Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3 The device is not guaranteed to function outside of its operating conditions. 4 Measured on JESD51-7, 4-layer PCB. 10/17/2014 MPS Proprietary Information.
