Description

MPL

Optimized Performance with MPS Inductor

The MP3438 is a highly integrated boost converter with a 1.2MHz fixed frequency and a wide input voltage (V_IN) range. The MP3438 starts up from a V_IN as low as 2.7V, and can support up to a 2A switching current limit with integrated, low on resistance (R_DS(ON)) power MOSFETs.

The MP3438 adopts constant-off-time (COT) control to provide fast transient response. The cycle-by-cycle current limit on the low-side MOSFET (LS-FET) prevents current runaway, and the high-side MOSFET (HS-FET) eliminates the requirement for an external Schottky diode. The MP3438 supports an automatic pass-through function when V_IN exceeds the set output voltage (V_OUT-SET). This function supports high efficiency, even when the input exceeds the regulated output.

Full protection features include configurable V_IN under-voltage lockout (UVLO) and over-temperature protection (OTP). The MP3438 is available in an SOT583 (1.6mmx2.1mm) package.

Optimized Performance with MPS Inductor

The EVL3438-TL-00A is an evaluation board designed to demonstrate the capabilities of the MP3438, a 1.2MHz, fixed-frequency, high-efficiency, fully integrated, synchronous boost converter with a wide input supply range.

The MP3438 starts from an input voltage (V_IN) as low as 2.7V and supports up to 2A of switching current limit with integrated, low on resistance (R_DS(ON)) power MOSFETs.

The MP3438 adopts a constant-off-time (COT) control topology to provide fast transient response. The MP3438 also supports automatic pass-through functionality when V_IN exceeds the set output voltage (V_OUT-SET), which can support high efficiency even while the input exceeds the output regulation.

The MP3438 is available in a SOT583 (1.6mmx2.1mm) package.

It is recommended to read the MP3438 datasheet prior to making any changes to the EVL3438-TL-00A.
