TD1720 TD泰德代理 PWM 耐壓16V 20A 詳細說明 |
|

General Description
The TD1720 is a voltage mode, fixed 300kHz switching
frequency, synchronous buck converter. The TD1720 allows
wide input voltage that is either a single 5~12V or two supply
voltage(s) for various applications. A power-on-reset (POR)
circuit monitors the VCC supply voltage to prevent wrong
logic controls. A builtin soft-start circuit prevents the output
voltages from overshoot as well as limits the input current.
An internal 0.8V temperature-compensated reference
voltage with high accuracy is designed to meet the
requirement of low output voltage applications. The TD1720
provides excellent output voltage regulations against load
current
variation.
The controller’s over-current protection monitors the output
current by using the voltage drop across the RDS(ON) of
low-side MOSFET, eliminating the need for a current sensing
