MP1497SGJ-Z

Monolithic Power Systems · DC-DC Converters · TSOT-23-8

MP1497SGJ-Z from Monolithic Power Systems, in a TSOT-23-8. 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 SS passive Soft-start pin: connect an external capacitor to program the soft-start time, which charges with an internal 11µA current source (5µA to 17µA range) until the 0.8V reference is reached.
2 IN power_in Supply voltage input for the 4.5V-to-16V input rail; decouple with C1 and connect using a wide PCB trace.
3 SW power_out Switch output node, to be connected using a wide PCB trace.
4 GND power_in System ground and reference ground for the regulated output voltage; connect to GND with copper and vias.
5 BST passive Bootstrap pin: a capacitor between SW and BST forms the floating supply for the high-side driver, and a 10Ω resistor between SW and the BST capacitor is strongly recommended to reduce SW spike voltage.
6 EN/SYNC input Enable input: drive high to enable the regulator, and apply an external clock in the 300kHz-to-2MHz range to synchronize the switching frequency.
7 VCC power_out Internal 5V bias supply output that must be decoupled with a 0.1µF-to-0.22µF capacitor placed close to the VCC and GND pins; capacitance must not exceed 0.22µF.
8 FB input Feedback input connected to the tap of the external output divider; the oscillator frequency is lowered when FB falls below 400mV to prevent current-limit run-away during a short circuit.
