TB7102AF

Buck DC-DC Converter IC

The TB7102AF is a single-chip buck DC-DC converter IC. The

TB7102AF contains high-speed and low-on-resistance power

MOSFETs for the main switch and synchronous rectifier to

achieve high efficiency.

Features

•

Enables up to 1 A of load current (I ) with a minimum of

OUT

external components.

•

High efficiency (η = 95% typ.)

Weight: 0.017 g (typ.)

(@V = 5 V, V

= 3.3 V and I

= 300 mA)

OUT

•

Operating voltage (V ) range: 2.7 V to 5.5 V

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

Uses internal phase compensation to achieve high efficiency with a minimum of external components.

Allows the use of a small surface-mount ceramic capacitor as an output filter capacitor.

Enable threshold voltage : V

= 1.5 V, V

= 0.5 V(@V = 5 V)

IL(EN) IN

IH(EN)

Housed in a small surface-mount package (PS-8) with low thermal resistance.

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

This product has a MOS structure and is sensitive to electrostatic discharge. Handle with care.

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

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.
