PMP9379: ±15V @ 500mA, 18 ~ 42V in, Buck

PMP9379 reference design is a positive and negative 15V output supply capable of delivering 0.5A per rail using the LM46002. The input voltage range is 18V to 42V in. PMP9379 uses external circuitry to ensure that the +/-15V output track each other, i.e. the output voltage above and below 0V are well controlled and accurately balanced.

This board has the capability to externally synchronize the regulators to an external clock. It is recommended that the synchronization clock pulse is AC coupled and is no less that 2V peak respective to the regulators Reference (0V for the Buck, -15V for the Buck boost inverter). The abs max for the synchronization clock pulse is 5.5V. Please refer to Datasheet of the LM46002 for more details regarding clock synchronization. Synchronization is an option not a recommendation.

The PMP9379 is a four layer board with overall dimensions of 3.1” (78mm) x 3.4” (86mm). The copper weight is 1 oz. on the outer layers and 0.5 oz. the inner layers.
