Communications infrastructure equipment employs a variety of power system components. Power factor corrected (PFC) AC/DC power supplies with load sharing and redundancy (N+1) at the front-end feed dense, high efficiency DC/DC modules and point-of-load converters on the back-end.
A preferred power supply architecture for DSL applications is illustrated in Fig. 2. A push-pull converter is used to convert the 48V input voltage to +/-12V and to provide electrical isolation. Synchronous buck converters powered off of the +12V rail generate various low-voltage outputs.
This challenging business environment has spawned new distributed voltage bus standards, such as the recent +12V Intermediate Bus Architecture (IBA). The deployment of low-cost unregulated (open-loop) bricks to convert from the -48V bus to a standard +12V intermediate bus has allowed new low cost Point-of-load (POL) modules to be used.
These small form factor POL modules, now available in Single In-line Package (SIP) and surface mount device package (SMD), provide a cost-effective means of providing systems loads with multiple low
