Monolithic Power Systems MP3437GRP
The MP3437 is a 600kHz, fixed-frequency, highly integrated, synchronous boost converter with a wide input range. The MP3437’s input voltage starts as low as 2.7V and supports up to 20W of load power from a 1-cell battery with integrated low RDS(ON) power MOSFETs. The MP3437 utilizes a constant-off-time (COT) control topology, which provides fast transient response.| Part No. | MP3437GRP |

DESCRIPTION
The QFN package has a MODE pin that supports the selection of pulse-skip mode (PSM), forced continuous conduction mode (FCCM), and ultrasonic mode (USM) under lightload conditions. 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 need for an external Schottky diode. The MP3437 supports automatic pass-through mode when the input voltage (VIN) is greater than the set output voltage (VOUT_SET) in PSM. Full protection features include programmable input under-voltage lockout (UVLO) protection and over-temperature protection (OTP). The MP3437 is available in a QFN-10 (2mmx2.5mm) package and a TSOT23-8 package.FEATURES
