DESCRIPTION
The TPS60151 is a switched capacitor voltage
converter which produces a regulated, low noise, and
low-ripple output voltage (5V) from an unregulated
input voltage. It maintains 5V regulation even when
V_IN is greater than 5V.
The 5V output can supply a minimum of 140mA
current with a small 2X2 QFN package.
TPS60151 operates in skip mode when the load
current falls below 8mA under typical condition. In
skip mode operation, quiescent current is reduced to
90µA.
Only 3 external capacitors are needed to generate
the output voltage, thereby saving PCB space.
Inrush current is limited by the soft start function
during power on and power transient states.
The TPS60151 has built-in current limit and output
reverse current protection that are ideal for HDMI,
USB OTG and other battery powered applications.
