1. LTM8049IY——Product Overview

The LTM8049IY is a highly integrated isolated DC/DC μModule converter with flyback topology from ADI (Analog Devices Inc.). The device integrates transformers, power switches, controllers, and compensation circuits, significantly simplifying the isolated power supply design process.The LTM8049IY's compact BGA package (15mm × 11.25mm × 4.92mm) makes it ideal for space-constrained applications.

2. LTM8049IY——Technical Specifications
Input Voltage Range: 3.1V to 32V (supports wide range industrial power supplies or battery powered systems).
Output Voltage: ±5V to ±12V (flexible configuration of positive and negative outputs via external resistors).
Isolation Performance:
- Isolation Voltage: 2500V_RMS (for 1 minute), meets medical/industrial safety standards.
- Operating isolation voltage: _1200VDC (continuous operation).
Output Power: 2W maximum (75% to 85% efficiency typical).
Temperature range: -40°C to +125°C (for harsh environments).
Protection Functions: Over-current Protection (OCP), Over-temperature Protection (OTP), Soft-start (10ms).

3. LTM8049IY——Core Advantages
The core value of LTM8049IY is reflected in the following aspects:
High integration: built-in transformer and MOSFETs, reducing external components by 90% and accelerating the design cycle.
Strong isolation capability: _2500VRMS isolation voltage for medical equipment (e.g., patient monitors) and industrial systems (e.g., PLC isolated power supplies).
Wide Input Voltage: Supports 3.1V to 32V input, compatible with 12V/24V bus or Li-ion battery power supply scenarios.
Bipolar out: can generate positive and negative symmetrical voltages to power analogue circuits such as operational amplifiers and ADCs.

4. LTM8049IY——Typical Application Scenarios
The LTM8049IY has a wide range of applications in the following fields:
Industrial Automation:
Provide isolated power supply for sensors (e.g. pressure/temperature sensors).
Isolated CAN bus, RS-485 communication interface, ground loop noise suppression.
Medical electronics:
Isolated power supply modules for ECG devices, blood glucose meters, etc. that need to comply with the IEC 60601 standard.
Test and Measurement Instruments:
provides low-noise ±12V power supply for high-precision data acquisition systems (such as oscilloscope front-end).
New Energy Systems:
Isolates control circuits and power modules in photovoltaic inverters.

The LTM8049IY is a Dual SEPIC/Inverting μModule® (power module) DC/DC Converter. Each of the two outputs can be easily configured as a SEPIC or Inverting converter by simply grounding the appropriate output rail. The LTM8049IY includes power devices, inductors, control circuitry and passive components. All that is needed to complete the design are input and output caps, and small resistors to set the output voltages and switching frequency. Other components may be used to control the soft-start and undervoltage lockout.

The LTM8049IY is an ideal isolated power solution for medical, industrial and communication systems due to its high integration, strong isolation capability and wide input range.
