BM2P134H-Z集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

General Description

This series IC is a PWM type DC/DC converter for

AC/DC which provides an optimum system for various

electrical product. It supports both isolated and

non-isolated devices, enabling simpler design of

various types of low power consumption electrical

converters.

This series also has a built-in starter circuit that can

withstand up to 730 V, which contributes to low power

consumption. Since current mode control is utilized,

current is restricted in each cycle and excellent

performance is demonstrated in bandwidth and

transient response. Switching frequency is fixed at 65

kHz, 100 kHz or 130 kHz. At light load, the switching

frequency is reduced and high efficiency is achieved. A

frequency hopping function is also built-in, which

contributes to low EMI. In addition, this product has a

built-in super junction MOSFET which has a withstand

voltage of 730 V.
