MP3216GJE-P

MP3216 36V, 1.3MHz, 0.75A Step-up Converter With Output Disconnect The Future of Analog IC Technology DESCRIPTION FEATURES The MP3216 is a monolithic step up converter integrating a 0.75A, 0.6Ω internal switch. The MP3216 uses current mode, fixed frequency architecture to regulate the output voltage, providing fast transient response and cycle by cycle current limit.          The MP3216 includes under-voltage lockout, over voltage protection and thermal overload protection preventing damage in the event of an output overload. In addition, the MP3216 can disconnect all loads from input DC power supply. The output short circuit protection prevents the Schottky diode and IC from damage. The MP3216 is available in small 6-pin TSOT23-6 package and 5-pin TSOT23-5 package. Internal 0.6Ω Power MOSFET Up to 36V Output Voltage 1.3MHz Fixed Switching Frequency 42V Over Voltage Shutdown Cycle-by-Cycle Over Current Protection UVLO, Thermal Shutdown Output Disconnection Output Short Protection Available in TSOT23-6, and TSOT23-5 Packages APPLICATIONS    Portable Applications Handheld Computers and PDAs Digital Still Cameras All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.

(TJ) ............... +125C MP3216 Rev. 1.02 2/8/2017 (4) θJA θ JC Notes: 1) Exceeding these ratings may damage the device. 2) The maximum allowable power dissipation is a function of the maximum junction temperature TJ(MAX), the junction-toambient thermal resistance θJA, and the ambient temperature TA. The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD(MAX)=(TJ(MAX)TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB. www.MonolithicPower.com MPS Proprietary Information.
