CAPUF Embedded’s DC-DC LDO modules provide a pin-to-pin compatible alternative to existing linear regulators – the LM7805, for example – while exhibiting significantly reduced heat output, eliminating the need for a heatsink while retaining a standard TO-220 form factor in your design. This enables smaller, lighter end products in applications that require voltage step down, such as power supplies, battery chargers, solar power supplies, microcontroller-related applications, and motor drivers.
The heart of CAPUF Embedded’s module is a Texas Instruments DC-DC Converter IC, and these solutions come as a 16 x 13 mm board with 3 pins for integration into your design. Both modules offer DC-DC operation at 600 kHz, >91% peak efficiency, 3 A peak current, and protections against output short circuit and overtemperature.
| Part Number | Input Voltage (V) | Output Voltage (V) | Current (A) | Power (W) |
| CE-DC-DC-LDOA-3.3 | 4.5-15 | 3.3 | 1.8 | ~6 |
| CE-DC-DC-LDOA-5.0 | 6.5-15 | 5.0 | 1.2 | ~6 |
Due to the extremely low cost of these devices, small quantities of free samples are not economically viable for most shipping locations. That said, CAPUF Embedded are open to conversation with engineers, so apply below if you envision a commercial application for this space-saving power solution.
