Product Details
The MAX635 is a fixed output -5V, inverting DC-DC converter
with high efficiency and low operating current.
The MAX635 only requires 3 external components, a diode, capacitor and an inductor
for basic inverting operation. Low battery detection is included on the chip.
The operating current is only typically 80µA.
Features
- Preset -5V, -12V, -15V Output Voltages
- Adjustable Output with 2 Resistors
- 80µA Typical Operating Current
- 3 External Components
- 85% Typical Efficiency
- Low Battery Detector
