TB7102F
Step-down DC-DC Converter IC
The TB7102F is a single-chip step-down DC-DC converter IC.
Equipped with a built-in high-speed and low on-resistance power
MOSFET, and utilizing a synchronous rectifier circuit, this IC can
achieve high efficiency.
TB7102F
Features
• Capable of high current drive (I_OUT = maximum of 1 A),
using only a few external components
• High efficiency (η = 95% )
(@V_IN = 5V, V_OUT = 3.3V, and I_OUT = 300 mA).
SON8-P-0303-0.65A
Weight : 0.017 g (typ.)
• Operating voltage (V_IN) range: 2.7V to 5.5 V
• High oscillation frequency of 1 MHz (typ.), making it possible to use small external components.
• Uses internal phase compensation, achieving high efficiency using only a few external components.
• A small surface mount-type ceramic capacitor can be used as an output smoothing capacitor.
• Housed in a small surface-mount package (PS-8) with low thermal resistance.
• Under voltage lock out (U.V.L.O), Heat protection, and Over Current Protection is built into.
