HA17451AP Datasheet Switching Regulator Controllers For DC/dc Converters

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HA17451AP/HA17451AFP Switching Regulator Controllers for DC/DC.

General Description

The HA17451 is a dual-channel switching regulator controller IC.

Each channel contains the basic circuits for controlling a PWM-type switching-regulator power supply.

Both channels are integrated onto the same chip.

Key Features

  • Low dropout voltage of on-chip 2.5V voltage reference: Vdrop = 0.2 V (typ) Operates throughout wide supply voltagerange: 3.3 V to 40 V Large maximum output current: 50 mA (max) Undervoltage lockout circuit High threshold voltage: 3.15 V (typ) Low threshold voltage: 2.98 V (typ) Low current drain: 1.5 mA (typ) Operates at wide range of oscillator frequencies: f OSC = 1 kHz to 300 kHz Dead time adjustable through full duty cycle range Surface-mount package (.
