TB7107FN Key Features
- Enables up to 2 A of load current (IOUT) with a minimum of external ponents
- High efficiency: η = 87% (typ.) (@VIN = 12 V, VOUT = 3.3 V and IOUT = 0.7A)
- 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 ℃)
- Because of an external phase pensation element, the optimal phase pensation according to the output
- Allows the use of a small surface-mount ceramic capacitor as an output filter capacitor
- Housed in a small surface-mount package (PS-8) with low thermal resistance
- Soft-start time adjustable by an external capacitor
