The LTM8062EV#PBF belongs to the PMIC - Battery Chargers category. An evaluation board with an operating temperature range of -40 to 125°C, it is a current mode step-down synchronous monolithic µModule regulator with integrated switching MOSFET and high current inductor. It is designed to generate an output voltage of 0.5V - 5.5V and requires an input voltage range of 4V - 40V.
The output current of the LTM8062EV#PBF is configurable with external components, allowing up to 8A of continuous current. It is housed in an 8-pin μDFN (3 x 3mm) package, with EMI filter and a 2-stage power supply transformer, effectively reducing external components and board space. The regulator also has integrated features that enable sequencing between multiple LTM8062EV#PBF regulators or other voltage sources.

The main applications for the LTM8062EV#PBF are advanced intelligent chargers, DC/DC converters, and POL DC/DC converters. It is also ideal for use in a diverse range of automotive applications including electronic control modules, 48V systems, air conditioning systems, and electric power steering. These applications are typical for the use of the regulator due to its wide operating temperature range and high efficiency over a wide load range, wherever battery charging and power conversion is necessary.

The operating principle of the LTM8062EV#PBF is based on current mode control architecture. The switching frequency is internally operating at 1.2MHz with a minimum duty cycle of 15%. Soft-start is included and is adjustable, decreasing the inrush current at startup. The output voltage is measured with an internal ADC, with an accuracy of ±5mV, and is used in maintaining a stable output voltage throughout the input voltage range. This is crucial for a successful battery charging process.

The main features of the LTM8062EV#PBF include an internal EEPROM for storing operating configuration, two stage power supply transformer, 100kHz Low-Noise Pulse Width Modulation (PWM) Mode, and Internal Temperature Shutdown with Hysteresis. An external sense resistor can also be provided for current sensing, allowing for comprehensive power management which includes power-on reset, under voltage lockout (UVLO), and over current protection (OCP).

The LTM8062EV#PBF is a highly reliable device with excellent performance. It meets the latest safety requirements, such as ISO7637 and Automotive Electronics Council (AEC) -Q100. Its high efficiency, low Noise PWM, wide temperature operating range, and high current output make it an essential component in applications requiring a reliable power source.
