The TLV6208x family devices are small buck converters with few external components, enabling cost effective solutions. They are synchronous step-down converters with an input voltage range of 2.5 and 2.7 (2.5 V for TLV62080, 2.7 V for TLV62084x) to 6 V. The TLV6208x devices focus on high-efficiency step-down conversion over a wide output current range. At medium to heavy loads, the TLV6208x converters operate in PWM mode and automatically enter power save mode operation at light-load currents to maintain high efficiency over the entire load current range.

To address the requirements of system power rails, the internal compensation circuit allows a wide range of external output capacitor values. With the DCS-Control™ (Direct Control with Seamless transition into Power save mode) architecture excellent load transient performance and output voltage regulation accuracy are achieved. The devices are available in 2-mm × 2-mm WSON package with Thermal Pad.
