MAX16904
Bootstrap Capacitor for High-Side Driver (0.1μF)
Voltage Supply Input. Connect a 4.7μF ceramic capacitor from SUP to PGND. Place the
capacitor very close to the SUP pin. For the TSSOP-EP package, connect both SUP pins
together for proper operation.
Buck Switching Node. LX is high impedance when the device is off. For the TSSOP
package, connect both LX pins together for proper operation.
Power Ground. For the TSSOP-EP package, connect both PGND pins together for proper
operation.
Buck Regulator Voltage-Sense Input. Bypass OUTS to PGND with a 10μF or larger X7R
ceramic capacitor.
Open-Drain Power-Good Output. External pullup resistor required for automatic SKIP
mode operation.
Sync Input. SYNC allows the device to synchronize to other supplies. When connected
to GND or unconnected, SKIP mode is enabled under light loads. When connected to a
clock source or BIAS, forced PWM mode is enabled.
+5V Internal Logic Supply. Connect a 2.2μF ceramic capacitor from BIAS to GND.
Analog Ground
Enable Input. EN is high-voltage compatible. Drive EN HIGH for normal operation.
No Connection. Not internally connected.
Exposed Pad. Connect EP to PGND. Do not use EP as the only ground connection.
