Component qualification in accordance with JEDEC and industry
standards to ensure reliable operation over an extended
temperature range. This includes, but is not limited to, Highly
Accelerated Stress Test (HAST) or biased 85/85, temperature
cycle, autoclave or unbiased HAST, electromigration, bond
intermetallic life, and mold compound life. Such qualification testing
should not be viewed as justifying use of this component beyond
specifiedperformance and environmental limits.
The TPS6211x devices are a family of low-noise synchronous step-down dc-dc converters that are ideally suited
for systems powered from a 2-cell Li-ion battery or from a 12 V or 15 V rail.
The TPS6211x is a synchronous PWM converter with integrated N-channel and P-channel power MOSFET
switches. Synchronous rectification is used to increase efficiency and to reduce external component count. To
achieve highest efficiency over a wide load current range, the converter enters a power-saving, pulse-frequency
modulation (PFM) mode at light load currents. Operating frequency is typically 1 MHz, allowing the use of small
inductor and capacitor values. The device can be synchronized to an external clock signal in the range of 0.8
MHz to 1.4 MHz. For low noise operation, the converter can be operated in PWM-only mode. In the shutdown
mode, the current consumption is reduced to less than 2
A. The TPS6211x is available in the 16 pin (RSA)
QFN package, and operates over a free-air temperature range of –55
°C to 125°C.
