First VID controller with adjustable start-up current for core-voltage regulators

The LM10011 power management controller with 4- and 6-bit voltage identification (VID) interfaces is the first of its kind designed to operate along with a point-of-load regulator to adjust the core voltage (VCORE) of a VID-enabled processor, such as the company's C6000 power-optimized DSPs and KeyStone multicore DSPs. The part also features 1% output voltage accuracy and adjustable output current during start-up.

The controller operates over a 2.97 to 5.5-V input voltage range. It can be used with any point-of-load regulator that has a feedback node, such as the company's 15-A LM21215 and 25-A TPS56221 synchronous buck regulators. The LM10011 offers 16 pin-programmable current output options during start-up. Offered in a 10-pin QFN package the part measures 3 x 3 x 0.5-mm. ($0.60 ea/1,000 available now)
