TPS60151 5V/140mA Charge Pump Device

• 2.7V to 5.5V Input Voltage Range

• Fixed Output Voltage of 5.0V

The TPS60151 is a switched capacitor voltage

converter which produces a regulated, low noise, and

• Output Reverse Current Protection

low-ripple output voltage (5V) from an unregulated

• X2 Charge Pump

input voltage. It maintains 5V regulation even when

• 1.5 MHz Switching Frequency

is greater than 5V.

• Maximum Output Current : 140mA

The 5V output can supply a minimum of 140mA

• 2X2 QFN With 0.8mm Height

current with a small 2X2 QFN package.

• Typical 90 µ A Quiescent Current at no Load

TPS60151 operates in skip mode when the load

Condition (Skip mode)

current falls below 8mA under typical condition. In

skip mode operation, quiescent current is reduced to

• Hardware En/Disable Function

90 µ A.

• Built-in Soft Start

Only 3 external capacitors are needed to generate

• Built-in Under Voltage Lock Out Protection

the output voltage, thereby saving PCB space.

• Thermal and Over Current Protection

Inrush current is limited by the soft start function

during power on and power transient states.

• USB OTG

The TPS60151 has built-in current limit and output

reverse current protection that are ideal for HDMI,

• HDMI

USB OTG and other battery powered applications.

• Portable Communication Devices

• Personal Digital Assistance

• PCMCIA Cards

• Cellular Phones

• Handheld Meters
