Up0104s Datasheet -

While the exact pin functions can vary slightly based on the variant (such as the UP0104P, UP0104T, or UP0104R), a standard power management IC layout within this specific uPI family typically segments pins into three functional areas: Power Inputs/Outputs ( VINcap V sub cap I cap N end-sub VOUTcap V sub cap O cap U cap T end-sub

Receives the primary input power supply, often connected to the +5V standby ( +5VSB ) rail.

Specified for an extended range of -40°C to 105°C . Up0104s Datasheet

According to manufacturer specifications and technical footprints cataloged on engineering networks like Veswin Electronics and Jotrin Electronics , the uP0104S balances tight voltage regulation with an industrial-grade thermal threshold.

The UP0104S datasheet highlights its versatility, with a range of applications across various industries, including: While the exact pin functions can vary slightly

| Pin | Name | Description | |-----|---------|-------------------------------------| | 1 | BOOT | Bootstrap cap for high-side gate | | 2 | UGATE | High-side MOSFET gate drive | | 3 | GND | Ground | | 4 | LGATE | Low-side MOSFET gate drive | | 5 | VCC | IC power supply (typically 5V or 12V)| | 6 | FB | Feedback input (to Vout divider) | | 7 | COMP | Compensation network (loop stability)| | 8 | PHASE | Switching node (between MOSFETs) |

Enable / Shutdown Pin. Logic HIGH turns the chip ON; logic LOW forces standby. FB / ADJ Feedback input. Monitors VOUTcap V sub cap O cap U cap T end-sub via a resistor divider network to control regulation. 6 POK / PGOOD Power OK open-drain indicator. Asserts high when VOUTcap V sub cap O cap U cap T end-sub is within regulation limits. 7 SS / BYP The UP0104S datasheet highlights its versatility, with a
