Overview
HOTCHIP HT3402S 40V/2A Constant Voltage & Constant Current Buck Converter IC General Description The HT3402S is a constant current, constant voltage power supply converter, which utilizes a voltage mode, a current mode circuit, and pulse width modulation (PWM) switching regulator control circuit An external sense resistor will set the charge current.
An internal resistor divider and precision reference set the final float voltage to 5.
1V with ± 3% accuracy.
With a 150 KHz switching frequency, HT3402S can provide a simple solution against EMI.
High efficiency up to 90% can also diminish heat significantly on all related components.
The HT3402S also possesses over-voltage protect, over-thermal protect, and short- circuit protect function.
At the beginning of the charge, the over- current circuit will limit the charge current not too high.
The HT3402S is available in a 8- pin SOP8 package Features  Wide Input Supply Range: 10V to 40V  ±3% Charge Voltage Accuracy；  High Eff...
