TPS923653 - Boost / Buck-Boost LED Driver

This page provides the datasheet information for the TPS923653, a member of the TPS923652 Boost / Buck-Boost LED Driver family.

Description

The TPS92365x family is a 2-A / 4-A nonsynchronous Boost / Buck-Boost LED driver with 4.5V to 65-V wide input range.

By integrating the lowside NMOS switch, the device is capable of driving LEDs as well as charging batteries with high power density and high efficiency.

Features

  • 4.5-V to 65-V wide input range.
  • LED common cathode connection.
  • Integrated 150-mΩ MOSFET with typical 3-A / 6.5- A current limit.
  • Optional switching frequency: 100 kHz to 2.2 MHz.
  • Spread spectrum for TPS923653 and TPS923655.
  • Advanced dimming options:.
  • Analog dimming (256:1).
  • Fast PWM dimming (150-ns pulse width).
  • Hybrid and flexible dimming (2,000:1 at 20-kHz PWM, 10,000:1 at 4-kHz PWM, 1,000,000:1 at 120-Hz PWM).
