DC-E2H Datasheet: High-Efficiency DC-DC Conversion for Modern Electronics

Step 3: Layout considerations per datasheet.

• Place a 10µF electrolytic + 0.1µF ceramic at the input (as close as possible to pins 1 & 2).
• Place a 1µF ceramic at the output (pin 3 & 4).
• Keep output traces short to minimize radiated noise from the 100kHz switching.

• A: Usually not in detail. The DC E2H datasheet provides raw ripple data but not radiated emissions. For CE/FCC compliance, you must add external EMI filters (common mode choke + X2 capacitor).

Part 4: Practical Design Example Using DC E2H Datasheet

Scenario: You need to power an isolated CAN transceiver (5V, 100mA) from a 24V industrial bus. You select a DC E2H-24S05 (hypothetical 24V input variant). dc e2h datasheet

The DC-E2H is a high-efficiency DC-DC step-down (buck) converter module designed to provide a stable output voltage from a fluctuating input source. It is characterized by its wide input voltage range and its ability to maintain high efficiency even under light load conditions. Key Applications: Place a 10µF electrolytic + 0

8. Power & Thermal

| Parameter | Typical | |----------------------|-----------------------------| | Max Power | 25W (400G dual port active) | | Idle Power (L0s) | 8W | | Thermal sensor | 3x on-die (junction, PHY, PCIe) | | Operating temp range | 0°C to 105°C (Tcase) |

The SMD top-side marking DC=E2H identifies the highly popular Richtek Technology RT9193-18GB, a high-performance, ultra-low-noise CMOS Low Dropout (LDO) linear voltage regulator. Packaged in a compact SOT-23-5, this integrated circuit delivers a stable 1.8V output at up to 300mA.

Step 1: Check input current.

Using the typical efficiency (η = 80%): ( P_out = 5V \times 0.1A = 0.5W ) ( P_in = P_out / η = 0.5 / 0.8 = 0.625W ) ( I_in = 0.625W / 24V = 26mA )
