Diodes Incorporated AP61040 | Demoboard AP61040 EVM

Beschreibung

The AP61040 is a low current synchronous buck converter providing high efficiency, excellent transient response and high DC output accuracy. The ultralow Iq of the AP61040 that make it ideal for applications such as fitness wearables, health monitoring, Bluetooth, and other handheld devices. The AP61040 regulator is optimized to operate with 2.2μH and 10μF output capacitor. The buck provides at least 400mA output current and input voltage range of 2.15V to 5.5V. The current control scheme handles wide input/output voltage ratios and provides low external component count with outstanding performance in line/load transient response and seamless transition between buck and 100% duty cycle modes. The AP61040 provides 3 programmable output voltages between 0.6V to 3.3V selectable by one selection pin. The AP61040 also features UVLO, OTP, and OCP to protect the circuit. This IC is available in a small 1.17mmx0.77mm, 6 balls WLCPS package.
