BM2P016T
●General
The PWM type DC/DC converter (BM2P016T) for
●Features
PWM frequency : 65kHz
AC/DC provides an optimum system for all products
that include an electrical outlet.
BM2P016T supports both isolated and non-isolated
devices, enabling simpler design of various types of
low-power electrical converters.
PWM current mode method
Frequency hopping function
Burst operation at light load
Frequency reduction function
Built-in 650V start circuit
BM2P016T builds in a HV starter circuit that tolerates
650V, and it contributes to low-power consumption.
With current detection resistors for switching as
external devices, a higher degree of design freedom is
achieved. Since current mode control is utilized, current
is restricted in each cycle and excellent performance is
demonstrated in bandwidth and transient response. The
switching frequency is 65 kHz. At light load, the
switching frequency is reduced and high efficiency is
achieved. A frequency hopping function is also on chip,
which contributes to low EMI. We can design easily,
because BM2P016T includes the switching MOSFET.
