| Symptom | Likely Cause | |---------|---------------| | No output on one channel | EN pin low, faulty MOSFET, open bootstrap cap | | Output low (<0.6V) | Shorted FB to GND, damaged controller | | Output = VCC | High-side MOSFET shorted (check UGATE signal) | | Overheating | Inductor saturation, low-side FET not turning off | | Pulsing output | OCP triggered — check inductor/capacitor shorts |
: Integrated high-side and low-side MOSFETs to improve efficiency and reduce heat compared to traditional diode-based converters. Up0104s Datasheet
: Shuts down the device if the output voltage exceeds safe limits. | Symptom | Likely Cause | |---------|---------------| |
: In typical linear regulator configurations, the series is rated for approximately 2.4 A . : Prevents current spikes during power-up to protect
: Prevents current spikes during power-up to protect sensitive downstream components. Protection Mechanisms :
: Offers product details, stock availability, and quality control information for UIMICRO manufactured parts.
It typically requires a 10μF tantalum capacitor on the output to stabilize load transients and a 100nF ceramic capacitor on the input for noise filtering.
