HV9120/HV9123

High-Voltage, Current-Mode, PWM Controller

Description

Features

• 10 to 450V input voltage range

• <1.3 mA supply current

• >1 MHz clock

HV9120 and HV9123 are Switch-Mode Power Supply

(SMPS) controllers suitable for the control of a variety

of converter topologies, including flyback and forward

converter.

• 49% maximum duty version

Using an internal, high-voltage regulator, HV9120 and

HV9123 can derive a bias supply for starting-up and

powering a converter from a variety of power sources,

such as a 12V battery or the rectified AC (230 VAC)

line.

Applications

• Off-line high frequency power supplies

• Universal input power supplies

• High density power supplies

• Very high efficiency power supplies

• Extra wide load range power supplies

HV9120/HV9123 controllers include all essentials for a

power-converter design, such as a bandgap reference,

an error amplifier, a ramp generator, a high-speed

PWM comparator, and a gate driver. A shutdown latch

provides on/off control. Device power consumption is

less than 6 mW when shutdown.

HV9120 offers 50% maximum duty and HV9123 offers

nearly 100% duty.
