3 Description
The TLV62080 and TLV62084 devices are low cost
buck converters in small size with less external
components. 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 TLV62084) to 5.5 V.
The TLV6208x device focuses on high-efficiency
step-down conversion over a wide output current
range. At medium to heavy loads, the TLV6208x
converter operates in PWM mode and automatically
enters 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 large
selection of external output capacitor values ranging
from 10-µF up to 100-uF effective capacitance. 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 device
is available in 2-mm × 2-mm WSON package with
Thermal Pad.
