Pololu 9V, 300mA Step-Down Spannungsregler D24V3F9

Item number: PO2099

Manufacturer Part Number: 2099

The compact (0.4???0.5?) D24V3F9 switching step-down (or buck) voltage regulator takes an input voltage between 11?V and 42?V and efficiently reduces it to 9?V while allowing for a maximum output current of 300?mA. The pins have a 0.1? spacing, making this board compatible with standard solderless breadboards and perfboards.

Description

Overview

These buck (step-down) voltage regulators generate lower output voltages from input voltages as high as 42 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 90%, which is much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. This regulator is available with a fixed 3.3 V, 5 V, 9 V, or 12 V output, and two versions are available for each voltage, one with a 300 mA maximum output current (D24V3Fx) and one with a 600 mA maximum output current (D24V6Fx)

Formularende

The regulator has short-circuit protection, and thermal shutdown prevents damage from overheating. The board does not have reverse-voltage protection.

Features

· Input voltage: [output voltage + dropout voltage] to 42 V (see below for more information on dropout voltage)

· Fixed 3.3 V, 5 V, 9 V, or 12 V output (depending on regulator version) with 4% accuracy

· Maximum output current: 300 mA or 600 mA (depending on regulator version)

· 1.25 MHz switching frequency

· 2 mA typical no-load quiescent current (20 µA typical quiescent current with SHDN = LOW)

· Integrated over-temperature and over-current shutoff

· Small size: 0.5? × 0.4? × 0.1? (13 mm × 10 mm × 3 mm)
