TB7107FN - Buck DC-DC Converter

Description

Pin No.

Bootstrap pin This pin is connected to Bootstrap capacitor.

A 0.1 μF bootstrap capacitor is required between BOOT pin and LX pin.

Features

  • Enables up to 2 A of load current (IOUT) with a minimum of external components. SON8-P-0303-0.65A.
  • High efficiency: η = 87% (typ. ) (@VIN = 12 V, VOUT = 3.3 V and IOUT = 0.7A) Weight: 0.017 g (typ. ).
  • Operating voltage range: VIN = 4.5 V to 20 V.
  • Low ON-resistance: RDS (ON) = 0.2 Ω (high-side) typical (@VIN = 12 V, Tj = 25°C).
  • Oscillation frequency: fOSC = 380 kHz (typ. ).
  • Reference voltage: VFB = 0.8 V ±2.25%(@ Tj = 25 ℃).
  • Be.
