TP7661AB Tuowei DC-DC Converter BDC-DC Converter 5V

TP7661A/B DC-DC Converter

Product introduction

The TP7661 CMOS DC-DC converter is a low-power, easy-to-operate power chip. Double voltage use method: input negative voltage

When -1.0~-8.0V, it can generate -2.0~ -16V output; when input positive voltage is 1.0~ 8.0V, it can generate -1.0~ -8.0V output triple voltage

How to use: Input negative voltage -1.0~-6.0V, it can produce -3.0~ -18.0V output, input positive voltage 1.0~ 6.0V can produce -2.0~ -12.0V

output. Three temperature gradient adjustment voltages are available. The PIN pin is compatible with SCI7661. (The performance of TP7661B is the same as that of TP7661A except that it has no Vreg and RV functions, and its PIN pin is compatible with SCI7661)

Features

* High performance, low power consumption, ultra-low voltage startup

* Adopt soft breakdown technology to make product performance more stable and reliable

*The driving capacity is 50% higher than similar products_ *Voltage conversion range: the absolute value of the maximum input voltage is 1.0V~6.0V when the voltage is tripled, and the absolute value of the maximum input voltage is 1.0V~8.0V when the voltage is doubled.

The maximum voltage difference that the chip can withstand is 18.0V.

*Power conversion efficiency: 95% typical

*The maximum current consumption is 2μA when the chip power is turned off by an external signal

*Two pieces in series VIN=-5V, VOUT=-20V

*Chip built-in RC oscillator

*Package form-------SOP16L
