Product Description

Overview

This adjustable boost (step-up) voltage regulator generates higher output voltages (between 2 V and 5.25 V) from input voltages as low as 0.5 V, and it also automatically switches to a linear down-regulation mode when the input voltage exceeds the output. This makes it great for powering electronics projects from 1 to 3 NiMH, NiCd, or alkaline cells or from a single lithium-ion cell. Additionally, unlike most boost regulators, this unit offers a true shutdown option that turns off power to the load (with typical boost regulators, the input voltage will pass directly through to the output when they are disabled).

When boosting, this module acts as a switching regulator (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and has a typical efficiency between 70% to 90%. The available output current is a function of the input voltage, output voltage, and efficiency (see Typical Efficiency and Output Current section below), but the input current can typically be as high as 1.2 A. This regulator is also available with a fixed 3.3 V or fixed 5 V output, and very similar regulators are available in a much smaller size with a fixed 3.3 V or fixed 5 V output.

The regulator’s thermal shutdown engages at around 140°C and helps prevent damage from overheating, but it does not have short-circuit or reverse-voltage protection.

Features

Input voltage: 0.5 V to 5.5 V
Adjustable output voltage from 2 V to 5.25 V
True shutdown option that turns off power to the load
Automatic linear down-regulation when the input voltage is greater than the output voltage
1.2 A switch allows for input currents up to 1.2 A
Good efficiency at light load: <1 mA typical no-load quiescent current, though it can exceed 1 mA for very low input voltages (<100 µA typical quiescent current with SHDN = LOW)
Integrated over-temperature shutoff
Small size: 0.45" × 0.6"× 0.1" (11.5 × 15.3 × 2.5 mm)

Allerletzte Dreck oder Defekt

Der Step-Up-Converter entspricht nicht im geringsten den Angaben von Pololu und hängt sich bei verändernder Spannung ständig(bei langsamen Veränderungen von Spannung) auf womit das Teil überhaupt nicht zu gebrauchen ist. Erstens wird nicht im Ansatz die Effizienz erreicht, die angegeben wird, zweitens wird nicht der nicht der Ausgangsstrom nach Datenblatt erreicht und drittens hängt sich das Teil ständig bei Spannungsänderungen auf.
Bereits bei ca. 0.5 V unter der Ausgangsspannung ist die Effektivität bereits unter 50% und sinkt dann noch sehr drastisch.
Entweder ist das ein Betrug oder es liegt ein Defekt vor!
Es wird jetzt dann Retoure eingereicht!!!
