Description
LD7750EGR LeadTrend High Voltage Green-Mode PWM Controller 65kHz -0.3V to 30V SOP-7 RoHS
The LD7750E integrates several functions of protections,
and EMI-improved solution in a SOP-7, SOP-8 or DIP-8
package to minimize the component counts and the circuit
space.
The device provides functions of low startup current,
green-mode power-saving operation, leading-edge
blanking of the current sensing and internal slope
compensation. Also, the LD7750E features more
protections like OLP (Over Load Protection), OVP (Over
Voltage Protection), and OTP (Over Temperature
Protection) to prevent the circuit being damaged under the
abnormal conditions. The LD7750E features built-in
auto-recovery function for OVP on Vcc pin and OLP.
