HiperLCS^™Family

Integrated LLC Controller, High-Voltage

Power MOSFETs and Drivers

Product Highlights

Description

The HiperLCS is an integrated LLC power stage incorporating a

multi-function controller, high-side and low-side gate drivers,

plus two power MOSFETs in a half-bridge conﬁguration. Figure

1 shows a simpliﬁed schematic of a HiperLCS based power stage

where the LLC resonant inductor is integrated into the transformer.

Features

•ꢀ LLC half-bridge power stage incorporating controller, high and

low-side gate drives, and high-voltage power MOSFETs

•ꢀ Eliminates up to 30 external components

•ꢀ High maximum operating frequency of 1 MHz

•ꢀ Nominal steady-state operation up to 500 kHz

•ꢀ Dramatically reduces magnetics size and allows use of

SMD ceramic output capacitors

The variable frequency controller provides high efﬁciency by

switching the power MOSFETs at zero voltage (ZVS), eliminating

switching losses.

•ꢀ Precise duty symmetry balances output rectiﬁer current,

improving efﬁciency

•ꢀ 50% 0.3% typical at 300 kHz

VCCH

•ꢀ Comprehensive fault handling and current limiting

•ꢀ Programmable brown-in/out thresholds and hysteresis

•ꢀ Undervoltage (UV) and overvoltage (OV) protection

•ꢀ Programmable over-current protection (OCP)

•ꢀ Short-circuit protection (SCP)

•ꢀ Programmable dead-time for optimized design

•ꢀ Programmable burst mode maintains regulation at no-load and

improves light load efﬁciency

•ꢀ Programmable soft-start time and delay before soft-start

•ꢀ Accurate programmable minimum and maximum frequency

LLC Feedback Circuit

•ꢀ Single package designed for high-power and high-frequency

•ꢀ Reduces assembly cost and reduces PCB layout loop areas

•ꢀ Simple single clip attachment to heat sink

•ꢀ Exposed thermal pad connected to ground potential – no

insulators required between package and heat sink

•ꢀ Staggered pin arrangement for simple PC board routing

and high-voltage creepage requirements
