TEXAS INSTRUMENTS DC/DC Charge Pump Inverter 1.6V-5.5V 60mA SOT-23-5

The TEXAS INSTRUMENTS DC/DC Charge Pump Voltage Inverter features a variable switching frequency and generates an unregulated negative output voltage from an input voltage ranging from 1.6V to 5.5V. It is typically supplied by a pre-regulated supply rail of 5V or 3.3V.

Due to its wide input voltage range, this charge pump can be powered by two or three NiCd, NiMH, or alkaline battery cells, as well as a single Li-ion cell. It requires only three external 1µF capacitors to build a complete DC-DC charge pump inverter, simplifying circuit design and reducing board space. The device delivers a maximum output current of 60mA with a typical conversion efficiency exceeding 90% over a wide output current range.

Key Features

• Inverts input supply voltage
• Only three small 1µF ceramic capacitors needed
• Power save-mode for improved efficiency at low-output currents
• 65µA typical device quiescent current
• Integrated active Schottky-diode for start-up into load
• Green product and no Sb/Br

Designed for surface mount applications, this component features a compact SOT-23-5 package and operates reliably across a temperature range of -40°C to 85°C. Its high efficiency and minimal external component count make it an excellent choice for power management solutions in portable and sensitive electronic devices.
