1 Features 3 Description

The TPS63700 is an inverting DC/DC converter

1• Adjustable Output Voltage Down to –15 V

generating a negative output voltage down to –15 V

• 2.7-V to 5.5-V Input Voltage Range with output currents up to 360 mA, depending on

• Up to 360-mA Output Current input-voltage to output-voltage ratio. With a peak

• 1000-mA Typical Switch Current Limit efficiency of 84%, the device is ideal for portable

battery-powered equipment. The input voltage range

• Up to 84% Efficiency of 2.7 V to 5.5 V allows the TPS63700 to be directly

• Typical 1.4-MHz Fixed-Frequency PWM powered from a Li-ion battery, from 3-cell NiMH/NiCd,

Operation from a 3.3-V or 5-V supply rail.

• Thermal Shutdown The inverter operates with a fixed-frequency pulse

• Typical –19-V Output Overvoltage Protection width modulation (PWM) control topology. The device

• 1.5-μA Shutdown Current has an internal current limit, overvoltage protection,

and a thermal shutdown for highest reliability under
