Buck DC-DC Converter IC

TB7101F contains high-speed and low-on-resistance power

MOSFETs for the main switch and synchronous rectifier to

achieve high efficiency.

Features

•

small overloads such as minor short-term overcurrent, or overheating. The protective functions do not necessarily

protect Product under all circumstances. When incorporating Product into your system, please design the system (1)

to avoid such overloads upon the Product, and (2) to shut down or otherwise relieve the Product of such overload

conditions immediately upon occurrence. For details, please refer to the notes appearing below in this document and

other documents referenced in this document.

The TB7101F is a single-chip buck DC-DC converter IC. The

The product(s) in this document (“Product”) contain functions intended to protect the Product from temporary

Enables up to 1 A of load current (I

external components.

Fixed output voltage: V

A high 1-MHz oscillation frequency (typ.) allows the use of small external components.

Uses only an inductor and two capacitors to achieve high efficiency.

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 a low thermal resistance.

Undervoltage lockout (UVLO), thermal shutdown (TSD) and overcurrent protection (OCP)
