HA17384HPS Datasheet High Speed Current Mode Pwm Controller

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HA17384SPS/SRP, HA17384HPS/HRP, HA17385HPS/HRP High Speed Current Mode PWM Control IC for Switching Power Supply ADE-204-028A (Z) 2nd Edition Nov.

General Description

The HA17384S/H and HA17385H are PWM control switching regulator IC series suitable for highspeed, current-mode switching power supplies.

With ICs from this series and a few external parts, a small, low cost flyback-transformer switching power supply can be constructed, which facilitates good line regulation by current mode control.

Synchronous operation driven after an external signal can also be easily obtained which offers various applications such as a power supply for monitors small multi-output power supply.

Key Features

  • High-safety UVL circuit is used (Both VIN and Vref are monitored).
  • High speed operation:  Current detection response time: 100 ns Typ  Maximum oscillation frequency: 500 kHz.
  • Low standby current: 170 µA Typ.
  • Wide range dead band time (Discharge current of timing capacitance is constant 8.4 mA Typ).
  • Able to drive power MOSFET directly (Absolute maximum rating of output current is ±1 A peak).
  • OVP function (over voltage protection) is include.
