Product description
Product core features: Core
solution: TI TPS63020 chip
Voltage conversion: automatic switching between boost and boost, covering the full discharge cycle of lithium batteries ( 1.8 - 5.5V input) Three outputs
Jumper switching: 3.3V ( 1.3A ) / 4.2V (1A) / 5V ( 0.9A ) Energy
Efficiency Management Dual-mode: conventional mode (dynamic response priority) + power saving mode (light load efficiency > 90%) Ripple Control Full Ceramic capacitor design, no-load ripple as low as 5mVpp (industry 1/6)
Version Parameter & Pin Definition: Only Version V 1.00
Size: 17.4 × 26.2 mm
Switching Frequency: 2.4MH z
Operating Temperature: -40°C~85°C
Pin Definition:
VIN: Input positive ( 1.8 - 5.5V ) Reverse connection is strictly prohibited!
PS: Shorted = Power saving mode Remove LED to reduce power consumption again
EN: Suspended = Enable, Low = Off Do not ground! Jumper pads Voltage selection (3V3/4V2/5V) Multiple simultaneous shorting prohibited! User pain point solution Battery voltage drop caused by equipment crash 1.8V continuous regulated output ( 3.7V 1.8V throughout the regulated) traditional DCDC interference sensor signal 15mV ripple + 2.4MH z high frequency away from the ADC sampling band small size equipment space constraints 17.4 mm × 26.2 mm + vertical welding to save space
Q1: Why does it consume power when no load?
