The TPS6040x is a family of devices that produce an unregulated negative output voltage from an input voltage range of 1.6 V to 5.5 V. The device typically provides 5 V or 3.3 V due to a preregulated supply rail with a wide input voltage range, two or three NiCd , NiMH or alkaline batteries, and a lithium-ion battery powered. Only three external 1-F capacitors are required to build...

describe The step-down family charge pumps of the TPS6050x devices generate a regulated, fixed 3.3 V, 1.8 V, 1.5 V, or adjustable output voltage. Only four are required to build a small ceramic capacitor to complete a high-efficiency DC/DC charge pump converter. To achieve high efficiency over a wide input voltage range, the charge pump automatically selects between three different co...

illustrate The ZMD41201 is a fully integrated 13.56 MHz ISO15693 compliant wireless tag transponder circuit. "The on-chip EEPROM can write a reader in the downstream direction and read in the upstream direction by inductive coupling. Power is also extracted from the reader via inductive coupling. Due to the on-chip tank capacitance, the ZMD41201 requires only one external coil...

The ADM663/ADM666 precision voltage regulators feature a maximum quiescent current of 12 mA. They can be used to give a fixed +5 V output with no additional external components or can be adjusted from 1.3 V to 16 V using two external resistors. Fixed or adjustable operation is automatically selected via the VSET input. Low quiescent current makes these devices ideal for battery-p...

The TC7660 is a pin-compatible replacement for the industry standard TC7660 charge pump voltage converter. It converts a +1.5V to +10V input to a corresponding -1.5V-10V output, using only two low-cost capacitors, eliminating the inductor and its associated cost, size, and EMI. The on-board oscillator operates at a nominal frequency of 10kHz. Below 10kHz operation (lower power cur...

The TC7660H is a pin compatible, high frequency upgrade to the industry standard TC7660 charge pump voltage converter. It converts a +1.5 V to +10 V input to a corresponding -1.5V to -10V output, using only two low-cost capacitors, eliminating the need for an inductor and its associated cost, size, and EMI. TC7660H (instead of TC7660 at 10kHz at 120kHz), 1.0mF external capaci...

The TCM680 is a dual charge pump voltage converter for 2VIN and develops an output voltage - from 2VIN to a single +2.0V input voltage to +5.5V. Common applications include ±10V from a single +5V logic supply, and ±6V from a 3V lithium battery. The TCM680 is available in a space-saving 8-pin SOIC package that requires only four inexpensive external capacitors. Charge pu...
