SGM41286

LNB Supply with Tone Repeater/Synthesizer

and Programmable Cable Drop Compensation

GENERAL DESCRIPTION

FEATURES

This SGM41286 is a high-efficient boost power supply

providing a wide input voltage range of 7V to 14V and

two selectable 14V and 19V nominal output versions.

The device integrates the high-efficient low head room

architecture. It also can operate with acoustic noise free

and work with low power.

● 7V to 14V Input Voltage Range

● 500mA 14V/19V Output

● DiSEqC 1.X Compatible

● Programmable -1V/+0.4V Drop Compensation

● High-Efficient Low Head Room Architecture

● Acoustic Noise Free Low Power Operation

● Automatic Tone Repeater or Tone Synthesizer

● LDO Output and Low Out-of-Band Noise

● 200ms Current Limit Loading Surge Window

● Internal Short-Safe Over-Current Protection

● Internal Over-Temperature Protection

● Available in Green TDFN-3×3-8L and

SOIC-8 (Exposed Pad) Packages

The -1V/+0.4V drop compensation can be programmed,

allowing the use of external surge absorbing devices at

the output. This device employs the features like

internal short-safe over-current protection and

over-temperature protection.

The SGM41286 is available in Green TDFN-3×3-8L

and SOIC-8 (Exposed Pad) packages. It operates over

an ambient temperature range of -40℃ to +85℃.

● -40℃ to +85℃ Operating Temperature Range

OVERSTRESS CAUTION

ABSOLUTE MAXIMUM RATINGS

Stresses beyond those listed in Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to

absolute maximum rating conditions for extended periods

may affect reliability. Functional operation of the device at any

conditions beyond those indicated in the Recommended

Operating Conditions section is not implied.

This integrated circuit can be damaged by ESD if you don’t

pay attention to ESD protection. SGMICRO recommends that

all integrated circuits be handled with appropriate precautions.

Failureto observe proper handlingand installation procedures

can cause damage. ESD damage can range from subtle

performance degradation tocomplete device failure. Precision

integrated circuits may be more susceptible to damage

because very small parametric changes could cause the

device not to meet its published specifications.

RECOMMENDED OPERATING CONDITIONS
