K3304 Datasheet 2sk3304

Manufacturer: NEC (now Renesas Electronics)

Overview: TPS65170 .ti. SLVSA27 – OCTOBER 2009 LCD Bias Supply Check for Samples.

General Description

The TPS65170 provides a simple and economic power supply solution for a wide variety of LCD bias applications.

In typical display panel applications, the boost converter generates the display panel’s source voltage VS, the buck converter generates the system’s logic supply VLOGIC, and the two charge pump controllers regulate the external charge pumps generating the display transistors’ on and off supplies VGH and VGL.

By using external transistors to regulate the charge pump output voltage, power dissipation in the IC is significantly reduced, simplifying PCB thermal design and improving reliability.

Key Features

  • 8.6V to 14.7V Input Voltage Range 2.8A Boost Converter Switch Current Limit Boost Converter Output Voltages up to 18.5V Boost and Buck Converter Short-Circuit Protection 1.5A Buck Converter Switch Current Limit Fixed 750kHz Switching Frequency for Buck and Boost Converters Fixed Buck Converter Soft-Start Programmable Boost Converter Soft-Start Two Charge Pump Controllers to Regulate VGH and VGL Control Signal for External High-Side MOSFET Isolation Switch Reset Signal With Programmable Reset Pul.
