DESCRIPTION
290-kHz, Adaptive On-Time D-CAP MODE
The TPS51211 is a small-sized single buck controller
Control
with adaptive on-time D-CAP mode. The device is
4700 ppm/°C RDS(on) Current Sensing
suitable for low output voltage, high current, PC
Internal 1-ms Voltage Servo Soft-start
system power rail and similar point-of-load (POL)
power supply in digital consumer products. A small
Pre-Charged Start-up Capability
package with minimal pin-count saves space on the
Built in Output Discharge
PCB, while a dedicated EN pin and pre-set frequency
Power Good Output
minimize design effort required for new designs. The
skip-mode at light load condition, strong gate drivers
Integrated Boost Switch
and low-side FET RDS(on) current sensing supports
Built-in OVP/UVP/OCP
low-loss and high efficiency, over a broad load range.
Thermal Shutdown (Non-latch)
The conversion input voltage which is the high-side
FET drain voltage ranges from 3 V to 28 V and the
SON-10 (DSC) Package
output voltage ranges from 0.7 V to 2.6 V. The device
requires an external 5-V supply. The TPS51211 is
available in a 10-pin SON package specified from
–40°C to 85°C.
