PWM Type DC/DC Converter IC
with Integrated Switching MOSFET
BM2P0161K-Z
General Description
Key Specifications
Operating Power Supply Voltage Range
The PWM type DC/DC converter for AC/DC provides an
optimal system for all products that require an electrical
outlet. This IC supports both isolated and non-isolated
devices and enables simpler designs of various types of
a low power consumption electrical converters.
The built-in 800 V startup circuit contributes to low power
consumption.
Power supplies can be designed flexibly by connecting a
current detection resistor for the switching externally.
Current is restricted in each cycle and excellent
performances are demonstrated in a bandwidth and
transient response since a current mode control is
utilized. The switching frequency is 65 kHz by a fixed
method. At light load, the frequency is reduced and high
efficiency is achieved. A built-in frequency hopping
function also contributes to low EMI. A built-in 800 V
switching MOSFET makes designs easy.
