XC9236E2KDER-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9236E2KDER-G is a synchronous step-down DC/DC converter from the XC9236 series by Torex Semiconductor. It features a fixed output voltage of 2.0V and supports a maximum output current of 600mA. The device operates with an input voltage range of 1.8V to 6.0V and utilizes a 3MHz switching frequency. It employs automatic PWM/PFM switching control to maintain high efficiency across varying load conditions. The component is housed in a compact 6-pin USP-C-EP package, suitable for space-constrained portable electronics.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Features automatic PWM/PFM switching control for optimized light-load performance
• Includes internal soft-start and current control functions for stable operation

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronic devices requiring efficient power management
• Battery-powered equipment utilizing lithium-ion or lithium-polymer cells
• Embedded systems needing stable 2.0V logic supply rails
• Consumer electronics with strict size constraints

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and halogen-free status as per manufacturer standards. Confirm the fixed 2.0V output voltage matches the target circuit requirements, as this variant does not support external resistor adjustment. Ensure the 600mA load capacity aligns with peak system demands to prevent thermal throttling or regulation failure during high-current transients.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 2.0V output is required without external feedback resistors. The 3MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1.8V minimum input voltage for single-cell battery applications. The automatic PWM/PFM mode is advantageous for extending battery life in standby or light-load scenarios compared to pure PWM regulators.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9235/XC9236/XC9237 series of 600mA synchronous step-down converters. The XC9236 sub-series specifically distinguishes itself through automatic PWM/PFM switching control, balancing efficiency and ripple noise. It shares the same pinout and general architecture with the XC9235 (PWM only) and XC9237 (manual switchable) variants, facilitating design flexibility within the same product family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other XC9236 series variants with different fixed output voltages, such as XC9236E15DER-G (1.5V) or XC9236E3FDER-G (3.55V), provided the voltage level is adjusted. Cross-series replacements like the XC9235 require manual mode selection adjustments. Verify that any alternative maintains the 600mA current rating and compatible operating temperature range.
