Multi-Phase 55 V
Intersil (Milpitas, CA) has introduced two 55 V two-phase
synchronous boost controllers with integrated high-side and
low-side MOSFET drivers. The ISL78227 and ISL78229
simplify the design of high power automotive applications.
Operating from a 12 V battery supply, these devices boost the
output voltage to 24, 36, or 48 V for premium 200 to 800 W
trunk audio amplifiers, start-stop systems, and headlamp LED
strings. Features include:
n The ability to provide input/output voltage from 5 to 55 V,
and withstand transients up to 60 V.
n The ability to use peak current mode control for fast line
response with adjustable slope compensation.
n Configurability for single phase, 2-phase, and 4-phase
n An adjustable switching frequency from 50 kHz to 1.1 MHz,
and external synchronization.
n Two layers of over-current protection.
n Negative current protection.
n Average current limiting.
n Soft-on capability, which provides a smooth transition from
soft-start to full operation in CCM.
n Adaptive and programmable dead-time control.
n Selectable diode emulation and phase dropping.
n AEC-Q100 qualification for operation from -40° to +125°C.
BGA Socket Adapter
Ironwood Electronics (Eagan, MN) has announced that its
SFS-BGA200B-52 high performance socket allows a 0.65 mm
pitch, 11 x 14. 5 mm body, 12 x 22 array 200 ball BGA package
to be placed in socket and operated without compromising
performance in high speed applications. The Giga-snaP BGA
socket adapter pair consists of SFS-BGA200B-52, patented
female BGA sockets with BeCu pins assembled into a
substrate that matches the male pin adapter. Features include:
n RoHS compliance.
n Soldering to a PCB using standard soldering methods
n Construction of the BGA socket and adaptor with high
temperature polyimide and FR- 4 body.
n A physical length from the top connection point on the male
adapter to the solder ball on the female socket of 3 mm.
n Transmission of high frequency signals up to 20 GHz with -1
dB insertion loss.
n An operating temperature range from -55° to +160°C.
n A current rating of 3 A per pin.
