Str-z2062 Datasheet !!better!! -

If Pin 4 (VCC) doesn't reach its "startup threshold" (often due to a failed startup resistor), the IC won't turn on.

By integrating the control IC and the power MOSFET, the STR-Z2062 reduces the number of external components, leading to smaller, more robust power supply designs. str-z2062 datasheet

Before replacing the IC, check the high-wattage resistors connected to Pin 4. If they are open-circuit, the IC won't get the "kickstart" it needs. If Pin 4 (VCC) doesn't reach its "startup

It's important to note that a similar part number, , exists that functions as a low-dropout (LDO) voltage regulator, providing a fixed 3.3V output at up to 600mA . This variant operates on a low input voltage (2.7V to 5.5V) and is used in different, lower-voltage applications. When sourcing parts, be careful to distinguish the high-voltage STR-Z2062 from the low-voltage LDO variant. If they are open-circuit, the IC won't get
