GR5401A - 1.4A Boost

Description

The GR5401A is a high frequency, asynchronous boost converter.

The internal MOSFET can support up to 8 White LEDs for backlighting and OLED power application, and the internal soft start function can reduce the inrush current.

Features

  • 2.5V to 5.5V operating input voltage range Drives up to 8 series White LEDs 1.0MHz Fixed Switching Frequency Wide range for PWM dimming (200Hz to 200KHz) Internal 1.4A switching current limit Over Voltage Protection (OVP) Internal Soft-start Function Current limit and Thermal shutdown protection Under voltage Lockout.
