MP3398AGF-Z
Monolithic Power Systems · New Arrivals · TSSOP-16-EP
MP3398AGF-Z from Monolithic Power Systems, in a TSSOP-16-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | COMP | passive | Step-up converter compensation pin; connect a ceramic capacitor from COMP to GND to compensate the regulation control loop. |
| 2 | EN | input | Enable input; above 1.8V turns the part on, below 0.6V turns it off, and the pin must not float. |
| 3 | PWM | input | PWM brightness control input where average LED current equals Iset*D_dim; high level must exceed VPWM_HI (1.25V), low level below the threshold, weakly pulled to GND if floating, and tie to 1.25V<Vpwm<5V if PWM dimming is unused. |
| 4 | GND | power_in | Ground. |
| 5 | OSC | passive | Switching frequency set; a resistor from OSC to GND sets the step-up frequency, with the pin regulated to 1.23V. |
| 6 | ISET | passive | LED current set; a resistor from this pin to ground programs the current in each LED string, with the pin regulated to 1.225V and the pin not to be left open. |
| 7 | ADIM | input | Analog brightness control input accepting a PWM signal (>20kHz recommended) or a DC voltage of 0.4V to 1.5V to set LED current linearly from 0% to 100%, with an internal 10MΩ/100pF RC filter and weak pull-down to GND if floating. |
| 8 | LED4 | input | LED string 4 current input, the open-drain output of an internal dimming control switch; connect the string 4 cathode here. |
| 9 | LED3 | input | LED string 3 current input, the open-drain output of an internal dimming control switch; connect the string 3 cathode here. |
| 10 | LED2 | input | LED string 2 current input, the open-drain output of an internal dimming control switch; connect the string 2 cathode here. |
| 11 | LED1 | input | LED string 1 current input, the open-drain output of an internal dimming control switch; connect the string 1 cathode here. |
| 12 | OVP | input | Over-voltage protection input; connect a resistor divider from the output to program the threshold, with OVP mode triggered when the pin reaches 1.23V. |
| 13 | ISENSE | input | Current sense input that senses the voltage across the inductor current-sensing resistor for peak-current-mode control and cycle-by-cycle limit; tie to GND if unused in cascading and do not float. |
| 14 | GATE | output | Step-up converter power switch gate output that drives the external power N-MOS device. |
| 15 | VIN | power_in | Supply input powering the chip and step-up converter switch, driven with a 5V to 28V source and locally bypassed. |
| 16 | VCC | power_out | Internal 6V linear regulator output powering the external MOSFET gate driver and internal control circuitry; bypass to GND with a ceramic capacitor. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
