The LM2587S-ADJ/NOPB is a DC-DC step up, synchronous switching voltage regulator that is capable of increasing its input voltage to the output voltage through an internal MOSFET switch and a feedback voltage detection circuit. This particular voltage regulator is physically packaged in an adjustable 8-pin SMD (surface mount device) package and is rated for up to 2A of load current. It can be configured for a variety of applications, ranging from battery chargers, to on-board voltage regulators, to power supplies.

The LM2587S-ADJ/NOPB is a voltage regulator that uses pulse width modulation (PWM) to generate a constant output voltage from a varying input voltage. The output voltage is controlled by adjusting the feedback resistor to control the average on time of the output stage. Throughout operation, the device always compares the output voltage to a fixed internal reference voltage and adjusts the on time to maintain the set output voltage. The device also includes internal protection circuitry to prevent damage to the device or its surrounding components in case of an over-current or over-temperature condition.

The LM2587S-ADJ/NOPB is specifically designed to operate in discontinuous current mode (DCM), meaning the output stage will automatically turn off when no load is present. This feature allows for improved efficiency and reduces heat dissipated in the output switch. The device can also be configured for other load conditions such as continuous conduction mode (CCM) or light load operation. Additionally, the device supports an enable/disable input that allows for manual control of the output.

The LM2587S-ADJ/NOPB supports an adjustable output voltage range from 6.5 to 40V and includes an internal over-temperature shut off feature that helps prevent damage to the device or system components by automatically powering off when temperatures become too hot. The device also includes an under-voltage lockout that prevents the device from being powered on in the event of a low input voltage. The device’s enable/disable input also supports an enable/disable lockout to enhance the safety of the system.

The LM2587S-ADJ/NOPB is an ideal voltage regulator solution for a wide range of applications. Its high efficiency, adjustable features, and over-temperature protection make it a great choice for applications requiring an adjustable DC-DC converter. From consumer electronics to automotive applications, this versatile device can easily provide the necessary power for a variety of systems.
