PM6602 Datasheet 8-row 30-ma Led Driver

Manufacturer: STMicroelectronics

Overview: .. PM6602 8-row 30-mA LED driver with boost regulator, dual dimming mode, SMBus interface and DPST for LCD panel backlights Preliminary.

General Description

The PM6602 consists of a high-efficiency monolithic boost converter and eight controlled current generators (ROWs), specifically designed to supply LED arrays used in the backlights of LCD panels.

The device can manage a nominal output voltage of up to 36 V.

The generators can be externally programmed to sink up to 30 mA and they can be dimmed in two different modes: via a PWM signal (1% dimming duty-cycle at 20 kHz can be managed) or in SMBus mode.

Key Features

  • 2 dimming modes: SMBus or PWM Boost section.
  • 3.3 V to 28 V input voltage range.
  • Internal power MOSFET.
  • Internal +3.3 V LDO for device supply.
  • Up to 36 V output voltage.
  • Constant frequency peak current mode control.
  • 500 kHz to 2 MHz adjustable switching frequency.
  • Pulse-skip power saving mode at light loads.
  • Built-in soft-start feature.
  • Programmable OVP protection.
  • Stable with ceramic output cap.
