5mA~450mA Constant Current Regulator

HM72XX

5mA~450mA Constant Current Regulator

MAIN APPLICATIONS

INTRODUCTION

•

LED Light Bars

LED Bulbs

The HM72XX-series products are linear constant current

regulators. With simple features, the HM72XX are economical

devices designed to provide a cost-effective solution for

current regulation of LED applications. The HM72XXlets LEDs

work under stable current and avoid brightness unstable

caused by current change, while their low voltage reduces

power consumption.

LED Fluorescent Lights

LED Backlight

FEATURE HIGHLIGHTS

•

Wide output voltage range: 2V~40V

Negative temperature coefficient

Accurate sink current: ±3%

With function of negative temperature coefficient, HM72XX

can protect LEDs from thermal runaway at extreme current.

HM72XX also provides a wide constant current range from

5mA to 450mA.

–40 ^oC ~+85 ^oC operation temperature range

Packages of SOT23-3, SOT89-3, SOT223, and TO252 are

available.

Pb-free and green packages:

SOT23-3, SOT89-3, SOT223, TO252

Output current: 5mA~450mA

General Notes

APPLICATION INFORMATION

For improved readability, the specification contains many application data points. When application information is given, it is advisory and does not

form part of the specification for the device.

BARE DIE DISCLAIMER

All die are tested and are guaranteed to comply with all data sheet limits up to the point of wafer sawing. There is no post waffle saw/pack testing

performed on individual die. Although the latest modern processes are utilized for wafer sawing and die pick-&-place into waffle pack carriers,

H&M SEMI has no control of third party procedures in the handling, packing or assembly of the die. Accordingly, it is the responsibility of the

customer to test and qualify their application in which the die is to be used. H&M SEMI assumes no liability for device functionality or performance of

the die or systems after handling, packing or assembly of the die.

LIFE SUPPORT APPLICATIONS

These devices are not designed for use in life support appliances, or systems where malfunction of these products can reasonably be expected to

result in personal injuries. Customer using or selling these products for use in such applications do so at their own risk.

CONTENT DISCLAIMER

H&M SEMI believes the information contained in this document to be accurate and reliable. However, it is subject to change without notice. No

Note:

(1) The condition can be achieved with the test circuit only. The Current Accuracy may be affected by negative temperature

coefficient and inappropriate package.

(2) For HM7230/HM7235/HM7240/HM7245 high current applications, it is necessary to add a heat sink to lower the case

temperature to below 50^oC to guarantee the current accuracy of ±3%.
