Step-down DC-DC Converter IC

The TB7101F 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.

Features

only a few external components.

• High oscillation frequency of 1 MHz (typ.), making it possible to use small external components.

• Uses internal phase compensation, achieving high efficiency using only an inductor and two capacitors.

• Built-in current mode architecture with excellent fast load response.

• 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 a low thermal resistance.

• Built-in undervoltage lock out (U.V.L.O), heatprotection, and overcurrent protection.

Marking (Note 1)/Pin Assignment

Due to its MOS structure, this product is sensitive to electrostatic discharge. Handle with care.
