TI intros industry’s first VID interface controller with adjustable start-up current for core-voltage regulators

USA: Texas Instruments Inc. (TI) introduced a power management controller with 4- and 6-bit voltage identification (VID) interfaces. The LM10011 is the first VID controller designed to operate along with a point-of-load regulator to adjust the core voltage (VCORE) of a VID-enabled processor, such as TI’s C6000 power-optimized DSPs and KeyStone multicore DSPs.

The LM10011 enables TI’s DSPs to realize their full power savings capability to reduce power consumption in wireless infrastructure applications. The controller features industry-leading one-percent output accuracy and adjustable output current during start-up.

The LM10011 VID controller operates over a 2.97-V to 5.5-V input voltage range and is a cost-effective, easy-to-use solution. It can be used with any point-of-load regulator that has a feedback node, such as TI’s high-performance 15-A LM21215 and 25-A TPS56221 synchronous buck regulators. The LM10011 offers 16 pin-programmable current output options during start-up, allowing the DSP VCORE to power up various voltages to enable greater system flexibility and reliability.

The LM10011 controller joins TI’s family of high-accuracy VID products that include the LM10010, UCD9244, UCD9224, UCD9248 and UCD9222.

Key features and benefits of the LM10011 VID controller include:
* 16 selectable start-up current options offer flexibility for system operation and higher system reliability.
* One-percent output voltage accuracy is fully compliant with C6000 VID table.
* 2.97-V to 5.5-V input voltage range supports both 5-V and 3.3-V bus voltages.
* Pin-selectable VID format allows 4-bit and 6-bit VID patterns.
* Precision enable supports custom under-voltage lockout (UVLO).

The LM10011 VID controller is available in volume now from TI and its authorized distributors. Offered in a 10-pin QFN package that measures 3-mm by 3-mm by 0.5-mm, the LM10011 is priced at US$0.60 in 1,000-unit quantities
