LTC3537 Datasheet 600ma Synchronous Step-up DC/dc Converter And 100ma Ldo

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC3537 2.2 MHz, 600mA Synchronous Step-Up DC/DC Converter and 100mA.

General Description

The LTC®3537 bines a high efficiency, 2.2MHz step-up DC/DC converter with an independent 100mA low dropout regulator (LDO).

The step-up converter starts from an input voltage as low as 0.68V and contains an internal 0.4Ω switch and a 0.6Ω synchronous rectifier that disconnects from the output when disabled in shutdown.

A switching frequency of 2.2MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.
