Reference design for halogen transformer IC
20 October 2004
Power Electronics / Power Management
International Rectifier offers a complete reference design circuit for its IR2161 halogen transformer IC. The reference design is a pre-fabricated and proven circuit for halogen lighting applications, which can simplify the design process and streamline time-to-market. The 'electronic transformer' reference circuit features compensated load regulation, short circuit and overload protection with over-temperature shutdown, and is compatible with all dimmer types.
The IR2161 IC features adaptive deadtime control, which increases transformer reliability by continually maintaining soft switching, regardless of external conditions. It detects the point at which the DC bus voltage in the half bridge slews to 0 V and sets the low-side driver high. An internal sample and hold system allows approximately the same delay to be used to set the high-side driver high after the low-side driver has gone low.
