1. Features
2
Low EMI noise and small footprint (5mm ) using inductor-embedded ferrite substrate
High efficiency using synchronous rectifier technology at 3MHz operation
PFM/PWM automatic mode switching function
Smooth mode transient between PFM mode and PWM mode
with low-ripple-voltage PFM mode
2% DC voltage accuracy over full load current range
Wide input voltage range : 2.3~5.5V
Maximum Load Current: 600mA (depends on output voltage)
Fixed output voltage: 0.8V – 4V (factory setting, 50mV step)
Internal soft start, overcurrent protection
Better reliability at high temperature operation compared to typeA
2. Description
The LXDC2HN series is a low power step-down DC-DC converter, which is suitable for a space-limited or a
noise-sensitive application. The device utilizes an inductor-embedded ferrite substrate, and the substrate
eliminates radiated EMI noise and conduction noise efficiently.
By just putting input/output capacitors, it can be used as a LDO replacement. Its low noise feature and easy to
assembly feature assures reliable power supply quality.
The device works in PFM mode at light load and it extends the battery life. At heavy load, its control mode
changes to PMW mode automatically and it keeps high efficiency using synchronous rectifying technology.
The device keeps good output voltage accuracy even in PFM mode. It keeps 2% DC voltage accuracy over full
current range (0-600mA), and shows very smooth mode transient between PFM mode and PWM mode.
LXDC2HN series has resin top coast to make it easy to be picked up in factory assembly.
TypeF uses MLCC of X6S/X6T temperature characteristics, so it is suitable for applications which need higher
reliability or higher operating temperature.
