TPS82671 datasheet

Description

The TPS82671 device is a complete 600mA, DC/DC step-down power supply intended for low-power applications. Included in the package are the switching regulator, inductor and input/output capacitors. No additional components are required to finish the design.

The TPS8267x is based on a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. The MicroSiP™ DC/DC converter operates at a regulated 5.5-MHz switching frequency and enters the power-save mode operation at light load currents to maintain high efficiency over the entire load current range.

Features

1. 90% Efficiency at 5.5 MHz Operation

2. 17µA Quiescent Current

3. Wide VIN Range From 2.3 V to 4.8 V

4. 5.5MHz Regulated Frequency Operation

5. Spread Spectrum, PWM Frequency Dithering

6. Best in Class Load and Line Transient

7. ±2% Total DC Voltage Accuracy

8. Automatic PFM/PWM Mode Switching

9. Low Ripple Light-Load PFM Mode

NCP1400A datasheet

 

Description

The NCP1400A series are micropower step-up DC to DC converters that are specifically designed for powering portable equipment from one or two cell battery packs. These devices are designed to startup with a cell voltage of 0.8 V and operate down to
less than 0.2 V. With only four external components, this series allows a simple means to implement highly efficient converters that are capable of up to 100 mA of output current.

Features

• Extremely Low Startup Voltage of 0.8 V
• Operation Down to Less than 0.2 V
• Only Four External Components for Simple Highly Efficient Converters
• Up to 100 mA Output Current Capability
• Fixed Frequency Pulse Width Modulation Operation
• Phase Compensated Error Amplifier for Stable Converter Operation
• Chip Enable Power Down Capability for Extended Battery Life
• Pb−Free Packages are Available

Typical Applications:

• Cellular Telephones
• Pagers
