HA16341NT/FP, HA16342NT/FP
Redundant Secondary Switching Power Supply Controller
ADE-204-035C (Z)
Rev.3
Apr. 2001
Description
The HA16341NT/FP and the HA16342NT/FP are switching regulator control ICs for the off-line
converters of redundant power supplies.
The HA16342NT/FP is reverse current detection less version of the HA16341NT/FP.
The HA16341NT/FP have the functions of current sharing and hot swap control for redundancy. These
functions enable high efficiency and high reliability for switching power supplies.
Combination the HA16341 with the HA16141 is suitable for the redundant AC to DC converters.
Features
Secondary-side synchronous rectification control
Main switching controller
Dead-time adjustment for synchronous rectification MOS
Current share function with line resistance compensation
Hot swap power MOS FET control
Remote on/off function, FAIL output function
Synchronized switching with primary side
Soft start function
Maximum duty adjustment
Overcurrent limiting, overcurrent shutdown functions
Reverse current detection (only the HA16341NT/FP)
Light load detection
OVP function
VCC pin UVL function
