What are the key features of LTC3404MPMS8?
- 2.65 V to 6 V input range with 0.8 V to 6 V adjustable output covers Li-ion battery and USB-powered portable device rails at up to 0.6 A
- Synchronous rectification with current-mode PWM control delivers high efficiency across light and heavy loads, minimizing battery drain in portable systems
- Compact 8-pin MSOP package reduces PCB footprint for space-constrained wearable, IoT, and handheld device power supply designs
What is LTC3404MPMS8 used for?
The LTC3404MPMS8 is ideal for single-cell Li-ion battery-powered applications such as portable instruments, wireless sensor nodes, and IoT edge devices that require regulated 1.8 V or 3.3 V rails from a 2.65 V to 4.2 V battery. Its synchronous step-down architecture enables efficient conversion in handheld medical devices and GPS receivers where battery life is critical. The 6 V input ceiling also accommodates USB-powered and dual-cell NiMH-powered designs requiring compact, low-part-count power stages.

Frequently Asked Questions
What input voltage range does the LTC3404MPMS8 support and which battery chemistries is it compatible with?
The LTC3404MPMS8 accepts input voltages from 2.65 V to 6 V, covering single-cell Li-ion (2.7 V to 4.2 V), two-cell NiMH (2.0 V to 3.0 V with 0.65 V headroom), and USB 5 V bus supplies. This wide input range allows a single design to serve multiple battery platforms or USB-powered applications without component changes, simplifying portable product development.
What output current and voltage flexibility does the LTC3404MPMS8 offer for multi-rail portable designs?
The LTC3404MPMS8 delivers up to 0.6 A continuous output current with an adjustable output voltage from 0.8 V to 6 V set by an external resistor divider. This flexibility allows the same IC to generate 1.0 V core logic rails, 1.8 V memory rails, or 3.3 V peripheral rails from a Li-ion battery, supporting multi-voltage microcontroller and FPGA platforms in compact embedded designs.
How does synchronous rectification in the LTC3404MPMS8 extend battery life compared to diode-based step-down converters?
The LTC3404MPMS8 replaces the traditional catch diode with an internal synchronous PMOS switch, eliminating the 0.4 V to 0.6 V diode forward drop during the flyback phase. At 0.3 A output from a 3.6 V input to a 1.8 V rail, this synchronous topology typically achieves 85-92% efficiency versus 70-80% for diode-based designs, extending battery run time by 10-20% in continuously active IoT and sensor node applications.
